The SQLyog and the MySQL server I am connecting to are on 2 separate machines over the network. I already tried to extend the connect_timeout global variable to 60 seconds. However, the SQLyog version 12 is still generating the same connection fail message after the same amount of time. Interestingly, the connection could be establish successfully if I use an older version of SQLyog (version 8).
I have this message on SQLyog :
“Error No. 2013
Lost connection to MySQL server at ‘handshake waiting for initial
communication packet’, system error: 138
