I am installing Sitecore 9.3 XP1-CM on Windows 2016 Server. Trying to set up our UAT Servers.
The installation succeeded and I can see the login page.
But, if I try to login to the Sitecore Instance, the Identity server is showing "Sorry, there was an error". (nothing on Unauthorised)
I have everything in place including with valid URL. in the Sitecore.IdentityServer.Host.xml
There are NO logs anything which I can know why this is happening.
I have another instance running which was installed using XP0-SingleDeveloper and it is working fine.
Would appreciate any inputs on this.
