SuiteCRM 3CX CRM Integration

Hello Guys,

Im trying to connect my 3CX Instance with my SuiteCRM per API. My SuiteCRM is installed on my NAS with an docker image. When i send a test request with the 3CX Template Generator, it returns me this error:

System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
—> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure: RemoteCertificateNameMismatch, RemoteCertificateChainErrors

Does anyone have an idea? I already tried a lot of things but it just doesnt wanna work. Thanks!
