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.

I have a trivial VB script which I am using to connect to a MySQL database on a Windows Server (2012 R2).
It's all super simple, out of the box "connect to MySql example" stuff.
I have verified that MySQL is listening on all local IPV4 addresses. I can connect with MySQL workbench with the same parameters. Yet I get a weird error when connecting via my program:
An address incompatible with the requested protocol was used
My connect string is as follows:
"server=127.0.0.1;database=test;uid=xx;pwd=xx"
It appears the connection tries to use IPV6 when connecting. How is this possible?
I suspect some kind of firewall is modifying or blocking my network connection, but it is a "new" machine for me and I don't know what's installed.
The problem was due to an old MySQL Connector DLL (MySQL.Data.dll) version which was either incompatible with Windows (hence the networking error message) or the version of MySQL I'm running. After upgrading the dll, the connection worked properly.
This may help out someone who has a similar problem, as the error is highly misleading.
I am trying to connect Power Bi (Desktop version) with my online amazon mysql database. It demands for following information once you try to establish connection
Server: server ip
Database: database name
Username: mysql username
Password: mysql password
First time I received a bit lengthy error, which was because of unavailability of mysql-connector-net-6.6.5.msi. So I followed this link to solve the issue
Microsoft Power BI connect to mysql
After installing mysql-connector I am facing another error.
Whats wrong? One of my mates has successfully connected using the same credentials that I am using.
Okay, I just figured this out for myself. I'm able to connect directly to a MySQL database on port 3306. As I understand, it would be more secure to go through an SSH tunnel, but this doesn't work yet with Power BI.
So here are instructions for connecting directly:
First, let's make sure that everything besides the PowerBI connection is working.
1) Download and install the correct version of the MySQL/Net Connector. Right now, version 6.6.5 is the one that works. But from other forums, and from within PowerBI itself, I linked to other versions that did not work. (You will know it isn't working, because you probably won't be able to even open Get Data/MySQL Database/Connect.)
2) See if you can connect remotely to your database through some well established utility like MySQL workbench. If you can't,
- look at ports on the remote server. Here's a cool utility to check ports&IPs: http://www.yougetsignal.com/tools/open-ports/
- Check the permissions of the DB user. Realize that they may be affiliated with an IP address: 'username'#'ipaddress'. So that user can only connect for a particular IP.
- Check the bind address setting. In newer versions of mariadb, it should probably be commented out. I'm not sure about older version and pure mysql.
- other troubleshooting.
So after that's working, here are the settings which worked for me in MySQL:
go to Get Data/MySQL database/connect
Server: ipaddress:3306 (include ":port#")
Database: dbname
PowerBI interface. Select "Database" instead of "Windows"
Make sure you select Database instead of Windows.
Good luck.
Just a small tip. If you haven't already, restart the machine you just installed the connector on. I had to restart before it started working.
My solution for this was to add the port number to the server name/ip
eg. 192.168.0.1:4664
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.
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.
One of the client is reporting this issue happening in our application. NHibernate throws Unable to connect to any of the specified MySQL hosts in the middle of the app running, so it is not a mistake in the configuration. It happens randomly, but always when the transaction is opened.
I saw this:
NHibernate, MySQL, Windows Server 2003 -- connection problems
But the server in my case is Windows 2008. And app opens only single connection simultaneously. MySQL version is 5.5.28. Server is on the remove machine
Unfortunately the app requires the HW I do not have, and I cannot reproduce it locally.
Any ideas or directions I need to dig in?
Try connecting using the full directory name, e.g. instead of Server=SRV use
Server=SRV.yournetwork.com
It might be that is has trouble resolving the server name.
