This has also been going on for me aswell for a couple of hours now, still occurring. Literally any game I join, the error appears almost instantly without any delays. Do let me know if you get it working as I’m curious to see if it gets resolved.
Same, this has been going on since last night for me. Roblox staff seem not aware of this issue because they haven’t made a comment on this or made a quick fix yet.
Seems like Roblox Studio is also affected by this and I’ve noticed many complaining about it. This may be related to the Studio issue. Apparently developers are unable to open their places as they are greeted with this error.
It seems that Roblox has server pools, so when we reach out to Roblox endpoints they forward our connection to the best server for us for that purpose.
My guess is that one of the servers that we are being redirected to for game joining is improperly configured and leads to an error, others that aren’t getting this error are being forwarded to working ones.
