I was having credentials for this remote MS SQL database for quite a long time. The port for connection was 1433 and I was connected via "Microsoft SQL Server Management Studio".
After some time, my client changed the credentials and gave me the new ones. With these new credentials I can not establish a connection successfully and I got the following error:
I assume that the reason for this is the fact that in the new credentials, the port is different then the default 1433 port which "Microsoft SQL Server Management Studio" uses (they are using port 5555 now) and in the log screen I can not see a way to assign a port to which I want to connect:
The new credentials which I got from the client, I confirmed that are correct, since I'm able to use them and to establish a connection with a different software (HeidiSQL - where at the login screen I can specify a port), but I really need to use "Microsoft SQL Server Management Studio".
There are some things which I did, from the following link, but still not success.
