Claude OAuth Failures

27•tankenmate•5h ago

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!

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

Its resolved for me. Also (Graz, Austria). 2 minutes ago i got to logon again

A_D_E_P_T•5h ago

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.

Edited to add: Got kicked out again. It worked for about 5 mins.

vvolhejn•5h ago

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

tankenmate•5h ago

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...

Sx999•3h ago

Seems completely fixed without any /login relogin for me...

Same issue, resolved a few minutes ago but happened again.

MeijeSibbel•5h ago

Same issue.

batirch•5h ago

Confirmed from Germany.

Miffles201912•5h ago

Yes happend to me as well- I am so disapponted . User from Malaysia

dibbla•5h ago

getting the same issue

aj6718•5h ago

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

abendrothj•5h ago

"OAuth request failed" when trying to login too.

MarcBuilds01•5h ago

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.

mac_ek•5h ago

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).

PeterStuer•5h ago

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.
