Database error: connection failed!

My website URL is:

What I’m seeing is:

DATABASE ERROR: CONNECTION FAILED!

Unable to connect to the database!
Please contact your server-administrator.

When I visit my webmail I receive above message. I am not sure why. I was thinking it might be that my domain are proxied through cloudflare for security (ie my nameservers are pointing to cloudflare DNS) After reading a few similar issues and some googling, I am forced to think otherwise. My webmail was actually working before even with cloudflare proxying.

I’m using this software:
Cloudflare

Additional information:
My traffic goes through Cloudflare security

You need to wait until iFastNet fixes its mail server, and then RoundCube will be back online.
