Sitecore 10.2 Identity Server invalid_request Error While I was trying to log in to Sitecore content management, the below error was coming "Sorry, There was an error: invalid request". So after some investigation, I found that for the content management server I had a different hostname which I need to configure in Sitecore. Solution To solve this error go to <IdentityServer>\Config\production\Sitecore.IdentityServer.Host.xml and add one AllowedCorsOriginsGroup2 inside AllowedCorsOrigins . <AllowedCorsOrigins> <AllowedCorsOriginsGroup1>https://xx.xx</AllowedCorsOriginsGroup1> <AllowedCorsOriginsGroup2>https://xx-xx-xx.xx.xx</AllowedCorsOriginsGroup2> </AllowedCorsOrigins>
