Claude OAuth Failures

Posted by tankenmate on Friday November 13, 2026 @04:54AM
from the self-post dept.

Claude has started having serious OAuth errors and hangs, but nothing appears on the Claude Status site yet[0]. It's been several minutes now, not sure if its a blip or something more serious. Obv Claude is still reporting the issues with MS O365 connector; but not sure if it's related.

Thanks for posting. Was wondering it was just me or not.

Thanks for posting!

Facts from my end:

I got "Please run /login · API Error: 403 Attention Required! | Cloudflare" during a long task that had been running for 27 minutes 10 seconds.

I don't do any work related to Microsoft Office.

The login isn't working, it opens the browser with a URL starting with https://claude.com/cai/oauth/authorize?{etc} but just sits there with the little spinner.

I was able to login once, but later encountered the same error and also only get the little spinner

Yeah, I've noticed that I got booted from Claude Code and can't log-in again. (Graz, Austria.) Happened about 20 mins ago.

Anthropic just updated with an incident report: https://status.claude.com/incidents/nn11wk485zfn

Thanks for the heads-up. I was also just able to log-in.

If you're working on anything interesting, neighbor, feel free to shoot me an email. My email address is (temporarily) in my profile.

I managed to log in ~5 minutes ago but kicked out again now.

It seems to have resolved for me now; I retried the auth link and it worked now.

Getting this frequently today within the last 2 hours: > "Please run /login · API Error: 403 Attention Required! | Cloudflare"

even though CC answers normally in-between and even performed tool calls and everything. It's ferquent and sporadic, for a few chat messages it works, then again it doesnt...Very very weird.

EDIT: Even with this message showing CC generates messages and replies, so it's not a matter of being totally logged-off...

Same in India. It works for few minutes then you get logged out of Claude Code

"OAuth request failed" when trying to login too.

Re:Claude OAuth Failures by MarcBuilds01 on Friday November 13, 2026 @05:22AM (#50481257)

Same issue here, thrown out, oauth login failed. Clicking on cancel in Claude Code will throw you back into the session for another couple of turns.

I got logged out 5 times in last 30 minutes of work, mostly after finishing long background task. After few attempts I menaged to log in again but after 15 minute logged out again - (Cracow, Poland).

Re:Claude OAuth Failures by PeterStuer on Friday November 13, 2026 @05:28AM (#50481351)

Same here. Straight Claude Code with sub

● Please run /login · API Error: 403 Attention Required! | Cloudflare Worked for 20s · done 11:15 /login ⎿ Login successful ● Please run /login · API Error: 403 Attention Required! | Cloudflare Churned for 19s · done 11:16 /login ⎿ Login successful ● Please run /login · API Error: 403 Attention Required! | Cloudflare Crunched for 22s · done 11:16

Logon sometimes succeeds, sometimes fails with OAuth error.
