[OMS] Portal issues - HTTP Error 400

Hi,

Sometimes the OMS portal seems to have various issues, so I will write about some that I encounter.

For example "HTTP Error 400. The size of the request headers is too long"

Usually this error happens if there is a corruption in the browser cache or cookies.

 

What to try which usually solves the issue: clear the browser cache/cookies and browsing history : https://www.thewindowsclub.com/delete-browsing-history-cookies-data-edge

 

Workarounds:

-open browser in private mode (incognito)

-test across other browsers
