Greetigns everybody,

the Migration.pl unfortunately gives me the Could not connect to the source database, although I can in the OTOBO server

ssh ssh -L 0.0.0.0:3306:0.0.0.0:3306 root@otrsip but in OTRS server I can’t create a tunnel I get the following message:

bind: Address already in use
channel_setup_fwd_listener_tcpip: cannot listen to port: 3306

the installation is Docker based:

Thank you in advance for the help!!
