SharePoint Online - Bad Request - Header Field Too Long

[mh-dev]

Hi All,

Me and our users are getting this error frequently: 

Bad Request - Header Field Too Long

 HTTP Error 400. A request header field is too long.

There is a workaround to fix this by clearing browser cookies, but we cannot consider this as permanant solution. We also created a ticket and the engineer told as to use the workaround.

Anyone fixed this before? Is MS planning to fix this problem?

Thanks

You can also try using another browser. That fixed the issue for me.
