Getting HTTP 431 error when trying to initiate the OAuth on Jira Cloud


A couple of our users are getting HTTP 431 error when they initiate oauth on their Jira cloud instances.

The URL they're hitting is

I'm guessing this is due to the header size (?). Is there a limit on the header side on Atlassian side?

Hi Fatmeh,

I've seen this happening before, especially with Chrome. Usually, a clear cookies + cache does the trick.

Can you ask the users to try this?

If the error still persists after clearing the cache and cookies, please create a ticket with the Atlassian Access team. Most likely, a HAR file will also be required.


Thanks Claudiu. It looks like the users stopped seeing the issue on Friday.

Is there a set limit on the Atlassian side?

Had also the issue on Chrome, Safari worked. Followed @Claudiu Lionte 's recommendation and was able to work with it again. Thank you very much!

I was facing this issue. I opened Chrome in "incognito" mode and was able to log-in.
