Error 1: Cannot connect to the localhost, connection timed out.
Simply increase the timeout error in the MS Management Studio connection settings (increase from 30 t0 120 and remember to turn this back again to the default after the first connection). Fix the initial timeout connection and this can be changed afterward. Increased connection timeout to 120.
Error 2: Cannot connect “An exciting connection was forcefully closed by the remote host Sql Exception with error number 10054
Solution: Try to identify and understand your environment in order to resolve this issue.
- This error clearly shows that the problem is not the firewall or the remote connections, but the login process.
This was not resolved because connection seems to work but the authentication method I tried to use is not supported by the database instances and therefore did not work. I was trying to connect using Domain Account and this was not supported.
