Currently the DevForums are returning 504’s (Bad Gateway) or (Gateway Timeo0ut) on most devices.
This seems like it was an issue a few days ago.
Receiving “502 Bad Gateway” Requests - Forum Feedback / Forum Bugs - DevForum | Roblox
Now they are completely out.
This is probably an issue on Roblox’s end, I’m just making this post to warn them of it.
