Cant start confluence and connect through browser:8090

[Deleted user]

It was working until last month. I had also connected to SQL Server successfully that time.

But stopped working now. Not reaching Confluence page at all.

What does the log file say the problem is?  (On the server, <confluence home>/logs/atlassian-confluence.log is the place to start, but check the other files in that directory if that has no errors)

This error message seems to be the shut-down messages you get when Confluence is shutting down because it cannot connect to the database you've given it.

I would expect to see some connection errors higher up in the log, before it starts to shut itself down, but check the network connection and the database credentials first.
