vtiger cmr integration erroe

[vencato]

Hi,
when I try to integrate 3cx 15.5 with vtiger crm 7.1 in the test phase I get this error:
Request text: https: // "crmservername": 10443 / webservice.php? Operation = getchallenge & username = admin
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.

thanks

There is a problem establishing the HTTPS connection, because the SSL certificate from your server can't be validated by 3CX. Ensure that you're using a valid certificate.
