Groupshare 2020 web server reinstall - 404 error when logging in

Hello,

I have the same problém asi described here:

https://community.sdl.com/product-groups/translationproductivity/f/studio/21734/error-after-installing-group-share---login--error--an-unknown-error-occured

But there is no solutions.

I reinstalled Groupshare 2020 on our test server and get an error 404 when trying to login.

What is the solution?

Thank you very much.
