When running the installable cloud app, the Web API console displays the following error:
2021-01-27 01:28:32,240 ERROR PowerServer.Client.PowerServerClient.LogMessage [0] - MESSAGE: License Exception: Failed to login the license server. (Invalid_client) at PowerServer.SessionFacade.CreateSessionIdAsync(String appName, String clientEncryptString, CancellationToken cancellationToken))
Cause & Solution:
The "invalid-client" error occurs because the license code is invalid or the license code cached in the system has expired. Please try the following:
-
Check the license code included in the PowerServer project matches the one you obtained from the Appeon website;
-
Clear the PowerServer cache and then build and run the Web APIs again;
To clear the PowerServer cache, go to %SystemDrive%\Users\[username]\.nuget\packages, and delete the folders starting with "dwnet", "powerserver", "snapobjects", and "powerscript".
-
Make sure that PowerServer is connecting to the correct license servers: https://apips.appeon.com, https://apipsoa.appeon.com, https://apips.appeon.net, https://apipsoa.appeon.net, https://apips2.appeon.com, and https://apips2.appeon.net. If not, update the PowerServer.Core and PowerServer.Api NuGet packages to the latest version.
