Since upgrading to version 19.04 I can not open CQRLog. I receive this message:
Error during connection to database: TMySQL56 connection: Server connect failed.
This is from the mysql.err file:

Any suggestions to correct this error would be appreciated. Please be specific in any steps I need to take to make the correction, I am getting comfortable with the Linux file system and files but am not an expert.
