Hi Guys I am really struggling to deploy a asp.net core application from visual studio 2017 to plesk onyx 17.5.3

get the following error:

Connected to the remote computer ("example.co.za") using the specified process ("Web Management Service"), but could not verify the server’s certificate. If you trust the server, connect again and allow untrusted certificates. Learn more at: Web Deploy error codes.
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

tried adding

<AllowUntrustedCertificate>True</AllowUntrustedCertificate>

to my publishing profile

I get the same error even with lower versions of plesk
