We looked at our firewall and we are not seeing any blocked traffics. We even open up the firewall wide open for troubleshooting and still no go! It has been down over 2 weeks.

See this thread: Unexpected renewal failures during April 2024? Please read this!

It is likely that your firewall or another firewall in front of it is performing geo-based blocking.
