Answer 1

In my case I had the following by mistake in my connection string:

Encrypt=True

Changing to

Encrypt=False

Solved the problem

"Server=***;Initial Catalog=***;Persist Security Info=False;User  ID=***;Password=***;MultipleActiveResultSets=False;Encrypt=False;TrustServerCertificate=False;Connection Timeout=30;"
