I run MSSQL on a Ubuntu 22 machine in the same network. I can connect from SSMS to the database and I can execute queries from VS 2022 on that database. So I guess it is no user or firewall issue. Only if I try to debug some stored procedure (which I regularly do on my Windows localhost) I get this

and this

Has anybody an answer to that?
Thanks.

BTW: I searched the web but found no appropriate answer.
