Current behavior
The hosted nexushub seems to be down. When going to https://nexushub.co/wow-classic/ using Firefox and clicking on "Zandalar Tribe" (horde), I just see "Connecting to the NexusHub API...". In the console, firefox complains with various warnings and errors:

Firefox can’t establish a connection to the server at wss://auth.nexushub.co/ws.
Source map error: Error: request failed with status 503
Resource URL: https://nexushub.co/bundles/bundle.client.4a4a6ba48db53a79e462.js
Source Map URL: browser.js.map

Firefox can’t establish a connection to the server at wss://api.nexushub.co/ws.
Firefox can’t establish a connection to the server at wss://auth.nexushub.co/ws.

Network tab says that requests to wss://auth.nexushub.co/ws and wss://api.nexushub.co/ws are met with "503 Service Temporary Unavailable".

Expected behavior
To be brought to the server market information page.

Minimal reproduction of the problem
https://nexushub.co/wow-classic/ select Zandalar Tribe, horde side. Any other server/side should work though.

Hey, I can't reproduce the issue. Can you check if it still occuring for you? Could be a result of the database dowtime a few hours ago.

Alright so I did some testing. Turns out it was caused by some stale settings in a User Agent switcher firefox addon I had installed. Looks like the library used by this website to do websocket breaks when given a different UA than expected. That's a bit scary given U-A are on their way out... But at least I now have a working nexushub! Thanks :D

Could post the used user agent? That way I can reproduce it and hopefully fix this bug

[roblabla]

the UA that breaks it: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:71.0) Gecko/20100101 Firefox/71.0
The "Real" UA that fixes it: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

I'm using https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher-revived/ to test on Firefox nightly.
