I have been trying to access planner for the past week and been unable to because of this error message: I get the same one no matter how I try to sign in to planner, if I do it through outlook browser or google planner and try to sign in through the Microsoft website. I am using google chrome and recently updated to windows 11. I do not understand how to fix this, could anyone help?

Clear browser history fix the issue

Clear your Chrome browser history. This fix the problem for all of my users who suddenly start reporting the same issue.

Yang608 Delete "Cookies and other site data" and it should be enough.

Exactly same problem here, using Google Chrome. In MS Edge browser Planner shows up normally. I haven't tried in other browsers.

vesscog Great thanks, it works! Note that just selecting cleaning Browsing history seems not to work, I selected all and it worked, not sure which exact item played the trick but anyway.

Planner Error- Server Error in '/' Application.

Same error. Works in Safari and Firefox on Mac, or from Teams app, just not Chrome

  vesscog clear cache does get it back to working in Chrome, but a few days later , have to clear cache again. Edge doesn't seem to have this issue. Also other users don't have this issue in Chrome.

I'm getting the same. I did try in a private window (using Edge) and it worked. So far I haven't found anyone else having the issue in our company. I wonder if Microsoft is pushing a release....
