• Steps to reproduce the issue:"

We have Latest copy of ABP IO commercial V7.0 using MVC and EFCore. Everything is working fine on Local without any change. We are trying to run this application on azure, and when we click on login it successfully redirect to the Auth Server then after passing credentials and clicked on Login we are getting above error. Same Issue is for Public Web site login. We did required changes on azure as well. "RequireHttpsMetadata": "false", this value is et to false and "IsOnK8s": "true", set to true for Public Web project. After login we are running into this issue.

Could you please help us to resolve this issue ASAP.

"AuthServer": { "Authority": "authserver url", "RequireHttpsMetadata": "true", "ClientId": "PublicWeb", "ClientSecret": "1q2w3e*", "IsOnK8s": "true", "MetaAddress": "authserver url" },
