What will happen to the requests and/or the attempt to connect to the
database? Will it timeout and retry again? Will it cause the user to
fail to login? What are the possible side effects on this log?
Honestly, even though it is an INFO log, the mere fact that somehow
the request failed, I am very much concerned on it.

Then, what will happen? It's an ERROR type of log. What are the
possible side effects for this?

Thank you for your time again.
