SQL Server – Error 18456, Severity 14, State 8

Try going to the bottom of the SQL error log message below:

The connection failed for the user's sa. Reason: The password does not match the connection provided. [CLIENT: 172.16.30.227]

Error 18456, severity 14, state 8

Event 3221243928

There were not many details in the newspaper and wanted to make sure that there was no critical failure.

Thanks in advance.
