Sharepoint Migration Toll - sign-in failure

Question

Hi,
14 days ago I was using SPMT website migration tool normally without any problems, now I wanted to continue after vacation and I can't start the application.
After logging into my MS online account in SPMT, I verify the account in MS Authenticator, everything goes fine, but SPMT doesn't log me in and shows this error:
Application exit
The application will exit because of sign-in failure.
Please double-check and try again.
I tried restarting the server, reinstalling, setting proxy in config, but nothing helped.

Thanks for any help
Philip

Answer 2

Hi,

I had similar issue with the same error message and already resolved this issue.I can recommend you to check logs for this tool in this location:

C:\Users%username%\AppData\Roaming\Microsoft\MigrationTool\GlobalLog

My errors were:

Error happened in AAD login System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

After disabling SSL inspection for this server (in a network management) is everything fine.

Maybe it helps to someone :)
