I have a VPS with Windows 2008 R2 with IIS web server, MySQL database server. I have hosted around 100 of websites on this server. One of the hosted website is throwing following error message:
" mysql_connect() [function.mysql-connect]: Host 'MYSERVER' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' in C:\Domains\mydomain.com\wwwroot\include\config.php on line 21
Could not be connect to mysql"
This website hosted around 3 years ago. I have not made any changes in the code. But, all of a sudden, website has started throwing error message. After that, I have searched error logs and found following details:
ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'MYSERVER#123'') WHERE User=''root''' at line 1
I have restarted service as well as rebooted server. But, it has not resolved MySQL error.
I was able to re-produce this error on my test server. You should check following:
→ You will have to make sure that the user you have added in your connection string is able to login to mysql server with the password you have entered in connection string. So, make sure that the username and password is correct.
→ Make sure that you have entered correct servername for mysql. If you are using local mysql (installed in same server), you should use 'localhost' in connection string. If you are using remote mysql server, make sure that you have entered it in connection string properly and that user must have remote access.

I've tested everything, and every possible way.
I already disabled iptables, I did everything myself.
I gave joker permissions on all users and database in mysql.
And anyway, how can test https://cp.nationwarriors.com/ the error persists:
Fatal error connecting to mysql server.
SQLSTATE [HY000] [2003] Can not connect to MySQL server on '177.87.231.218' (111)
in localhost I get it.
I checked the door is normally open at https://www.yougetsignal.com/tools/open-ports/
After a Teamviewer session and a few tests we've discovered that the problem is with the hosters firewall.
You can telnet from every location to the database server, except from the webserver.
I have published the website on Arvixe system pointing to MySQL database.
When i try to access the website, its working fine, but somehow after some page accessing, it start giving the error as:
Server Error in '/' Application. A network-related or
instance-specific error occurred while establishing a connection to
SQL Server. The server was not found or was not accessible. Verify
that the instance name is correct and that SQL Server is configured to
allow remote connections. (provider: SQL Network Interfaces, error: 26
- Error Locating Server/Instance Specified)
I have pointed my website to MySQL database, but it is giving the error of SQl server.
For a check, when i run the website pointing to arxixe database from my local machine, its working absolutely perfect.
I have hosted the MySQL database onto Arvixe server itself.
Any help on this would be highly appreciated.
You will want to check 2 things:
1.You are using "localhost" or "127.0.0.1" in the connection string for the script on the server.
2.There may be another connection string in the code, that is connecting to the MSSQL server.
There is a 3rd option:
Contact Arvixe's support as they will have exact details of what would be happening.
Good luck!
I am a windows 7 user and I'm having an issue with MySQL and XAMPP.
I use the MySQL that comes with XAMPP. I have changed the root password of MySQL using XAMPP's security page. Then I tried to connect to the MySQL server via Netbeans.
To try to connect I clicked on MySQL server option in the database drop down of the services pane, I gave it some settings:
server host name:localhost
username:root
port:3306
password:(my sql password)
path to admin module:(http:'//')localhost/phpmyadmin
sql start path:D:\D-drive\xampp-portable\mysql\bin\mysqld.exe(also tried mysql_start.bat)
sql stop path:</b>D:\D-drive\xampp-portable\mysql\bin\mysqladmin.exe(also tried sql_stop.bat)
Then I right click on MySQL server at localhost [root] and select Connect, this is when I get an error:
Unable to connect to the MySQL server:
org.netbeans.api.db.explorer.DatabaseException: org.netbeans.api.db.explorer.DatabaseException: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server..
The server may not be running or your MySQL connection properties may not be set correctly. Do you want to edit your MySQL connection properties?
Changing localhost to 127.0.0.1 doesn't work either. I have the jdbc driver as well.
The fix that worked for me is as follows:
Please see that netbeans is an allowed program in your firewall as well as antivirus software
to check:
if netbeans startup page says "cannot connect to internet" then you must change your firewall and/or antivirus settings to allow it
I am using Delphi xe2 and I would like to know qhat this error is and by what means I need to get around this, I am attempting to connect my database application to a wamp server through a LAN connection and I seem to have the Hostname username password and port correct but when I attempt to log into the MySQL database I get this error:
(Exception EZSQLExeption in module VDB1.exe at 002A7A5C. SQL Error:
Host'My-PC' is not allowed to connect to this MySQL server)
Could you please give me a way to get around this? Thanks.
The error message states:
Host 'My-PC' is not allowed to connect to this MySQL server
And this would indicate that the SQL server is blocking your client based on its host name, 'My-PC'. So, you need to configure your MySQL server to allow connections from that host.
I was working on some tables in mysql, and out of no where, i got an error (Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.) Then i uninstalled xampp and tried to reinstall it. Then i got the error (phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.)
How can i get access again?
