admin UI login loop

[koo9]

Deployed admin UI and IDS to staging with SSL (behind traefik reverse proxy), when logging into the admin UI, after the consent screen, the redirect loop starts, it keep bouncing back and forth between signin-oidc and ids until 431 error, which is request header too large. been fighting this for a while, any idea why that happen?

here's the error log System.Exception: An error was encountered while handling the remote login. ---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 401 (Unauthorized). at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode() at Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler.GetUserInformationAsync(OpenIdConnectMessage message, JwtSecurityToken jwt, ClaimsPrincipal principal, AuthenticationProperties properties) at Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler.HandleRemoteAuthenticateAsync() --- End of inner exception stack trace --- at Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler`1.HandleRequestAsync() at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.StaticFiles.StaticFileMiddleware.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.CspMiddleware.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.MiddlewareBase.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.MiddlewareBase.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.MiddlewareBase.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.MiddlewareBase.Invoke(HttpContext context) at NWebsec.AspNetCore.Middleware.Middleware.MiddlewareBase.Invoke(HttpContext context) at Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware.Invoke(HttpContext context) System.Net.Http.HttpRequestException: Response status code does not indicate success: 401 (Unauthorized). at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode() at Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler.GetUserInformationAsync(OpenIdConnectMessage message, JwtSecurityToken jwt, ClaimsPrincipal principal, AuthenticationProperties properties) at Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler.HandleRemoteAuthenticateAsync()

then after that, the error is:

No access token found.

turns out to be the client secret mismatched for the admin UI client.
