How do I re-submit my vat return after QB could not connect to HMRC web site?

There are certain errors that prevent you from re-submit your vat return after QuickBooks could not connect to HMRC. If you happen to encounter one, I encourage posting it here. This way, I'll be able to lay out the appropriate solutions based on your current situation.
