I have a MS Access front end that connects to a MySQL database. When the computer running Access is on the same network it works fine but trying to do it remotely is not working.
I can connect with MySQL workbench so I know the port forwarding is setup correctly.
I can test the connection from the connector panel and it says its successful.
When I click OK the connector box disappears, Access freezes for a while, then the box reappears.
For troubleshooting purposes I also tried to connect over a VPN which produced the same results. Using the ip given by the vpn. I've also tried the ip of the host network.
Connection String:
[ODBC]
DRIVER=MySQL ODBC 5.2 ANSI Driver
UID=kristim
DFLT_BIGINT_BIND_STR=1
PORT=3306
DATABASE=awanacontrol
SERVER=****.****.com
It seems to have been a simple issue of starting from the beginning. I was trying to change the address of the already linked tables. In order to get it to work I needed to be sure to delete all linked tables and link them again with a new ODBC string with the DNS name.

I just set up a new MySQL database with the MySQL workbench & created a user for it with all necessary privileges. I am using this database for use with my php code. But I can't seem to connect to it on my live server (pages are hosted on windows server 2012). Everything works fine in my local environment with xampp and the new MySQL database is exactly the same as the xampp one. I think I am maybe using the wrong host name or something. As host name I copied the name that is displayed after "Host:" when you click on Server Status in MySQL workbench. The database name, user & password should all be correct. But when my code tries to access the db I get a "The domain page isn’t working. Domain is currently unable to handle this request."
You either have no network connection to the server at all or it is blocked due to firewall or routing misconfiguration.
If you do have network access in general, you might forgot to
FLUSH PRIVILEGES;
or you have not enabled networking over TCP, the default is to listen only to localhost (on unix systems via unix sockets, on microsoft I guess it's simply TCP).
Read about the following configuration parameter which will solve your networking issue:
bind-address
If you have a very old MySQL server version, the parameter is enable-networking but it shouldn't be the case anymore.
I am attempting to connect Tableau on a client (Windows 7) to a MySQL Server 5.6 (on Windows Server 2012 R2) that is hosting my data warehouse. This server is hosted on my university's network. Here is what I have done so far:
created a user that has privileges it needs (I ran GRANT ALL PRIVILEGES ON the user with FLUSH PRIVILEDGES, based on some other stack overflow posts)
made sure the host specified in the user table is "%"
made sure there was nothing in the my.cnf file that would prevent external connections (again based on another stackoverflow post)
ensured that the edition of MySQL running on the server is 64 bit, like the version of Tableau I'm running
I still get the "[MySQL][ODBC 5.3(w) Driver]Host 'vpn240-74.vpn.utah.edu' is not allowed to connect to this MySQL server" error. This same error is thrown when I try to telnet to the port on the server MySQL is listening on.
I have found that this error persists whether I am connected via a vpn or on campus. I can RDP to the server in question, ping it, and found the firewall rule for the port I am using, so I don't think there is anything network related that is stopping me.
All my stackoverflow research says that error means MySQL is convinced that the user is not allowed to connect from that specific hostname, but I get the same error whether I change the entry in the user table to be "%" or the specific hostname from the error message.
Also I see that the Tableau MySQL driver I installed is a lower version number than the MySQL instance I'm trying to hit (5.3 vs 5.6) but that is the newest driver on the Tableau site that I can find.
Any help greatly appreciated.
Have you tried making an ODBC connection in your computer to your MySQL server and testing it that way?
Tableau can then connect via an ODBC connection made rather than the explicit Tableau MySQL driver. In Tableau under More Servers... Other Databases (ODBC) shows up at the very bottom.
Im having trouble using the MySQL ODBC connector.
I have a MS access frontend that im trying to connect to a MySQL DB. It connects fine when running the frontend and DB on my dev machine.
I have moved the front end and DB onto the clients server. The clients assess the fornt end via a shared folder on the individual user PCs. I have set up a file DSN ODBC connection as below. When i open the front end on one of the clients PCs i get the ODBC--call failed.
How do i get the linked tables to look at the server MySQL DB considering ms access is not installed on the server. I have tried to set uo the file DSN via the users pc i.e. open linked table manager and open the File DSN get the ODBC--call failed on connect.
File DSN set up
[ODBC]
DRIVER=MySQL ODBC 5.3 Unicode Driver
UID=root
PASSWORD=root
DFLT_BIGINT_BIND_STR=1
PORT=3306
DATABASE=productionlist_be
SERVER=localhost
thanks in advance Kelly
Welcome to stack-overflow Kelly.
You are missing few points.
The MySQL database Server must be accessible by all your clients.
Either a local machine hosting MySQL server or from internet its up
to you
Must have a static IP or domain name.
Access Front-Ends should not be shared but sent to all of your clients/employees
(This way you are achieving true "multi user access" and thats the main idea behind front and back ends)
All of your client PC must have MySQL ODBC driver installed
All of your clients must have required version of Access or Access Runtime installed
Only after setting up all this, you can think about distributing your application to your clients.
Modify your File DSN replace the localhost with the MySQL Database server ip
like
SERVER=SERVER_NAME_OR_IP
Also it is best to refresh the odbc links via VBA code
you will find much help here:
How do you programmatically update a linked table in Access that will refresh data types too?
OR
Relinking database tables: Access, VBA
hope this helps to get started :)
I am trying to connect to MySql db using VS2010. I added my ip address in cpanel allow hosts. I also grabbed the IP address for the server where the database is hosted which is just my website.
So I go to server explorer, right click database connections and clicked on add a connection
I select .NET Framework Data Provider for MySQL for Data Source
for Sever Name I typed the IP address for my website where the Database is
Typed in the user name and password who has all the privileges, and entered the Database Name too.
When I hit test connection I always getting "Unable to connect to any of the specified hosts"
any advice is appreciated
Thanks
So, in order to connect to a MySql database from VS2010 see the link bellow:

Have you tried adding % as your access host under Manage Remote MySQL Access of your Cpanel?
Try this
http://zambalestechrealm.wordpress.com/2012/03/08/vb-net-remote-access-to-mysql-database-of-my-website-2/
It says
Goto Your site Cpanel, and look for MySQL remote access, in my case i put % in the list of user to access remotely to my database. ‘%’ percent means to allow all connection to connect to my MySQL database.
I have a MySQL instance running on a Linux box, and a Mac which also has Win7 (Bootcamp/VMWare). I can connect to the MySQL db from Navcat Lite for Mac with no problems, however, I prefer Toad. I installed Toad for MySQL for Win7 but it just CANNOT connect to the db. I installed ODBC for MySQL and it CAN successfully connect to the db, so it's not a firewall issue (I also tried disabling the firewall)
Here is a quick summary of what I see:
MySQL db running on Linux box, within my network, port 3306
Mac can successfully connect to the db through Navcat Lite
Toad for MySQL (Win 7) CANNOT connect to the db using a TCP connection (tried increasing connection timeout to 30 sec)
ODBC Driver for MySQL (Win 7) CAN connect to the db using the same credentials
Any help would be much appreciated!
Here is the error that Toad throws:
System.TimeoutException
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
Check this bug report. Might be what you are facing.

Taking in account your recent outcome from the packet sniffing, i do believe it is related to this bug report.
Toad seems to use the .net framework, according to the release notes it requires version 3.5 to be installed and the security policy set to unrestricted.
So, do you have .net 3.5 installed? if so, can you try to run toad as administrator?
PS: to set the security policy and i'm quoting from the link above:
To run Toad, the .NET security policy must be set to Unrestricted. To modify the security policy:
Select Control Panel from the Windows Start menu.
Double-click Administrative Tools.
Double-click Microsoft .NET Framework version Configuration.
Select My Computer, and then select the Runtime Security Policy
node.
Select Evaluate Assembly from the list of tasks in the right panel,
and locate and select Toad.exe in the File field.
Click Next and set the permission to Unrestricted.
Hope it helps, keep providing information.
I have the same issue with one my MySQL installations. I am able to connect using MySQL Workbench, but Toad for MySQL does not connect. Also, every application I created using MySQL .NET Connector also times out.
The solution I found was to connect the machines to the Internet and they connect instantly. I believe it has to do with the Connector and not Toad. Updating to a version beyond 5 should help.
Using freeware Toad for MySQL 8.0.0.296 (64 bit), instead using connection type TCP, use connection type SSH, insert database data like Host IP, user, password, default database and port. Also add SSH port, SSH Host IP, SSH user and password. Toad will emulate onnection directly to SSH console, the interface is the same, it works very fine, the error "Character set 'utf8mb3' is not supported by .Net Framework" is gone.
