Have you contacted support to have your IP range whitelisted at the firewall?

The first picture you posted appears to be an authorization issue or a timeout.

The CPU Bandwidth quota is indicative of an inefficient script. You may have a script running that is using far too many server resources.

If you are on HM, use the backup utility. It will display all your available SQL databases and then you can choose which one you want to backup. The backup utility will automatically gzip everything up and let you download.\

As for the second error, check the cpu_exceeded log in your tmp directory in the root directory. See what is causing the problem and how often the problem has been occuring. Might give you a clue to what's the problem.
