Is this the same issue that’s been resolved in this topic @spectrum?

I was able to pinpoint what the issue was! I had reached out to our managed Discourse support and they provided an IP address that we’d previously added to a blocklist on our WAF, due to a high amount of traffic from that address. Turns out that IP address was required to be allowed in order for Discourse to communicate properly. I’m so glad it was not an issue on Discourse’s end!
