i have a strange problem. First, newest msoledbsql_220.127.116.11_x64 Driver is installed. Further i tried several Versions of Heidi, same Problem.
If i go to Connection Manager, open a existing connection to MS SQL Express 2017, everything works fine. But if i use the same connection from Dropdown, or re-open Heidi the connection will be refused (takes to long etc.)
Server-Browser is enabled, it is a named Instance.
With another SQL-Server (real one, not Express) everything works fine...
Plz help me, tia
