Starting around 12pm eastern today our free trial form stopped working and I started looking into it. Seems we started getting a bunch of XML RPC 404 errors despite nothing changing in our code.
We’re getting this error in our logs:
XML-RPC: xmlrpcmsg::parseResponseHeaders: HTTP error, got response: HTTP/2 404
At the same time as this is happening though, it looks like the API calls are working fine on another one of our sites. Any idea what’s going on with the other server? I’m assuming it’s some kind of configuration change that we need to make to get XMLRPC running properly but I’m completely lost here short of rebuilding that entire integration with oAuth, and can’t seem to find help anywhere.
I’m aware we should rebuild for oAuth, but right now we can’t get any membership signups until this random issue gets resolved so a bandaid would be much preferred.
