Delphi11.3 - TRestClient - MSGraphAPI - Error 12029

[mvanrijnen 127]

Hello,

I just had to work on a project for the first time in D11.3, it uses TRestclient against the MSGRaph API.

Now i'm getting error 12029, probably some TLS problem, anyone got a quick solution?
Tried, .SecurityProtocols := [TLS12, TLS13] etc.  not working

 

Running on Windows 11 (21H2), updating to 22H2 right now.

When do  you get the error? 

During connect, authentication or later?

[mvanrijnen 127]

During the Execute of the post to get the token.

'https://login.microsoftonline.com/[clientname].onmicrosoft.com/oauth2/v2.0/token'

pff found it, there was a proxy server forced in debug mode.
