During the past days you might’ve been getting ERR_TOO_MANY_REDIRECTS and or Bad Request - Login session expired errors. This bug was introduced during last week’s cluster add-ons upgrade.
We have reverted the change that’s causing these issues. If you still encounter login problems, please make sure to delete your cookies and try again.
Note: We’re aware of a 2nd authentication-related issue, where you can get sudden 500 errors when your token’s TTL expires and it’s credentials don’t get properly refreshed. We’re still investigating this. Refreshing the dashboard will allow you to proceed (after re-login). The Grafana dashboard is not affected by this bug.
