To be up to date for upper versions and later visitors :

Currently I'm working on a win7 64bit having different tools on it including python 2.7.4 as a prerequisite for google android ...

When I upgraded from WB 6.0.8-win32 to upper versions to have 64bit performance I had some problems for example on 6.3.5-winx64 I had a bug in the details view of tables (disordered view) caused me to downgrade to 6.2.5-winx64.

As a GUI user, easy forward/backward engineering and db server relative items were working well but when we try to Database>Connect to Database we will have Not connected and will have python error if we try to execute a query however the DB server service is absolutely ran and is working well and this problem is not from the server and is from workbench. To resolve it we must use Query>Reconnect to Server to choose the DB connection explicitly and then almost everything looks good (this may be due to my multiple db connections and I couldn't find some solution to define the default db connection in workbench).

As a note : because I'm using latest Xampp version (even in linux addictively :) ), recently Xampp uses mariadb 10 instead of mysql 5.x causes the mysql file version to be 10 may cause some problems such as forward engineering of procedures which can be resolved via mysql_upgrade.exe but still when we try to check a db connection wb will inform about the wrong version however it is not critical and works well.

Conclusion : Thus sometimes db connection problems in workbench may be due to itself and not server (if you don't have other db connection relative problems).

It looks like there are a lot of causes of this error  My Cause   Solution In my case  the cause was that my server was configured to only accept connections from localhost  I fixed it by following this article  How Do I Enable Remote Access To MySQL Database Server   My my cnf file had no skip-networking line  so I just changed the line bind-address   127 0 0 1  to bind-address   0 0 0 0  This allows connections from any IP  not just 127 0 0 1  Then  I created a MySql user that could connect from my client machine by running the following terminal commands    mysql -u root -p mysql gt  CREATE USER  username   1 2 3 4  IDENTIFIED BY  password       - gt  GRANT ALL PRIVILEGES ON     TO  username   1 2 3 4  WITH GRANT OPTION      - gt   q  where 1 2 3 4 is the IP of the client you are trying to connect from  If you really have trouble  you can use     instead of  1 2 3 4  to allow the user to connect from any IP  Other Causes For a fairly extensive list  see Causes of Access-Denied Errors

I was in similar situations before and last time I found it was some Windows update issue not sure   This time  I opened MySQL workbench and found no connection to my local database  I cannot see my tables  but yesterday I could connect to the database   I found that my cause is that  after letting my computer sleeping for some time and wake it again  the mysql service is not running   My solution  restart the service named  mysql  and rerun the workbench  Restarting the service takes a while  but it works

The error occur because the mysql server is not starting on your computer  You should start it manually  Do following steps    Download and install wamp server according to your bit version 32bit or 64bit  in your       computer http   wampserver-64bit en softonic com   this link allows you to download wamp server for 64bit  As soon as you install it you can double click and run it   you can see a icon in the right hand of the taskbar It may be hidden  so you can click the arrow which show you the hide apps runing  So click the icon and go to Mysql Then go to Service and there you can find Start Resume Services click on it   And now it is done Open mysql workbench and see It will work

The issue is likely due to socket authentication being enabled for the root user by default when no password is set  during the upgrade to ubuntu 16 04   The solution is to revert back to native password authentication  You can do this by logging in to MySQL using socket authentication by doing   sudo mysql -u root   Once logged in   ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY  password     which will revert back to the native  old default  password authentication   Now use password as the password whenever required by MySQL

Did you try to determine if this is a problem with Workbench or a general connection problem  Try this    Open a terminal Type mysql -u root -p -h 127 0 0 1 -P 3306 If you can connect successfully you will see a mysql prompt after you type your password  type quit and Enter there to exit     Report back how this worked

I struggled with this problem for awhile and did several reinstalls of MySQL before discovering this   I know that MySQL server was running OK because I could access all my DB s using the command line   Hope this works for you   In MySQL Workbench  5 2 47 CE   click Mange Server Instances  bottom right corner   click Connection  in the Connection box select   Local Instance   ServerName  - root 127 0 0 1 3306   lt  Standard TCP IP    click Edit Selected     under Parameters  Hostname change localhost or 127 0 0 1 to your NetBIOS name  click Test Connection  If this works for you  great  If not change the hostname back to what it was
