Multi-Factor Authentication seems to be down

I am getting the following message instead of being able to enter the code from my phone.
Proxy error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request.
Reason: Error reading from remote server..
Anyone else who has enabled MFA having this issue?

Seems to be fixed. Either on the church end or mine. Cleared cache on my browser and it works now. But it also works on another browser that wasn't working before that I didn't clear the cache. Oh well. I'm in.

It could well have been a Sunday overload issue with headquarters.
