Answer 1

Thank you all for helping me with this problem.

This worked for me;

https://community.spiceworks.com/topic/514617-exchange-2013-unable-to-login-to-owa-ecp

This is the solution:
Using the commands :

Set-OWAVirtualDirectory -Identity "adminsrv\OWA (Default Web Site)" -FormsAuthentication $False -BasicAuthentication $True

Set-OWAVirtualDirectory -Identity "adminsrv\OWA (Default Web Site)" -FormsAuthentication $true -BasicAuthentication $True

Followed by IISreset and also to recycle the app pools for OWA and ECP

Hello @AtleJohansen-1588,

Have you tried to login in OWA and ECP from a different Computer/Mobile? Or from a different browser? In Google chrome, you can login in In-cognito mode to avoid any cookies to impact the connection.
The link given shows that you are getting an error message "Can't reach the page - ERR_Connection_Reset", which can be fixed by deleting the cookies from the browser
