Having the same issue, since this morning. Switching device and even switching internet connection did not solve issue. I am seeing 401 and 403 errors which makes me think that Nordic changed their firewall/network settings or something. Regardless https://docs-be.nordicsemi.com/api/user is not returning anything other than "401 Unauthorized" which is problematic.

Console:

I cannot find any email address for this issue. I hope nordic engineer on this portal see this and report to their Web Engineers

Ok so I investigated a bit more and now 100% sure it's nordic's issue.
When opening the page, text with error shows exactly in the same moment some random script throws an error in the console:

and `clustered_topics` looks like something that documentation may contain.
So searching the network requests there is this thing:

GET	https://docs-be.nordicsemi.com/api/bundle/ngl_004/page/GL/ngl_004/frontpage.html

and when searching it's response with `topic_cluster`, there is some:

And, there is null. So their endpoint responds with data that some frontend script does not expect or understand, therefore crashing.
So yes, it's nordic's problem, and I have no idea how to let them know via this portal.

Same issue here.
What I tried:
- clearing cache, cookies, locastorage and indexedDB
- previous step with turning VPNs on or off (USA and Germany locations)
- previous step with signing in or out from the account
- using incognito mode
- using browserling.com to access the website
- turning off uBlock origin extension in firefox
- trying different browser (firefox, safari, chrome)
- trying from a diffrent device (IOS safari)

So I think it's pretty much enough to say it's the issue on the nordic's side.
