Can't create or add extension on the online dev rig

I have been using the offline dev rig up until now and I wanted to move my project to the online one, however whenever I try to add an existing extension or create a new one and click save it always says “Failed to fetch” and does nothing.
I am using Chrome, I restarted it, and the computer as well as deleting the cache but it still says the same thing.

Usually a temporary issue with the TwitchAPI.

Try again later! Or now since it’s 11 hours later
