Description:
15:43:08 [ERR][    WQE backend]: Got an exception during connection: Bad handshake
15:43:08 [ERR][SQL Editor Form]: SQL editor could not be connected: Bad handshake
15:43:08 [ERR][SQL Editor Form]: Your connection attempt failed for user 'root' to the MySQL server at engineering-islam.dafater.biz:3306:
  Bad handshake

Please:
1 Check that MySQL is running on address engineering-islam.dafater.biz
2 Check that MySQL is reachable on port 3306 (note: 3306 is the default, but this can be changed)
3 Check the user root has rights to connect to engineering-islam.dafater.biz from your address (MySQL rights define what clients can connect to the server and from which machines) 
4 Make sure you are both providing a password if needed and using the correct password for engineering-islam.dafater.biz connecting from the host address you're connecting from

How to repeat:
It repeated after connecting to a remote server.
