I get an error message when I click on donations

I tried making a donation yesterday and again today but receive this error message when I click on donations -

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /donations/.

Reason: Error reading from remote server

Additionally, a 302 Found error was encountered while trying to use an ErrorDocument to handle the request.

I made two donations this morning, and did not receive any errors.

And I made one Saturday that completed today. I suspect the servers were busy Sunday, or one of them had problems and has probably been reset by now as Church employees have returned to work after the weekend.

I get the same message as above person

Additionally, a 302 Found error was encountered while trying to use an ErrorDocument to handle the request.
I have tried all weekend and the past couple of days.

By any chance are you using a proxy server? Sometimes company computers are set up that way, some security devices, or malware does that. I believe computers in a FHC use a proxy, but I don't think clerk computers do.
