Unable to connect to a DB2 Instance with SSL

Hi all,

Recently I'm having connection issues with a DB2 Instance after a password change. Normally I'd change my password in the connection settings and be done with it but now having errors with the SSL setting.

At first it  I received an unknown host error but after checking Data Sources//SSH/SSL I'd noticed that the use SSL checkbox was not checked.

Afterwards I received the following error message and I was unable to pinpoint to the root cause of this.
