Telnet on soap port for AES

If you need further help please log a support ticket via MSP.

@VamsiKrishnaR16655097to resolve the SOAP service failed error when configuring your PDC in an on-premises environment, you typically need to use Telnet to check connectivity on port 80 (HTTP) or port 443 (HTTPS). For example, execute telnet <PDC_IP_or_Hostname> 443 to verify if the HTTPS port is accessible. If your SOAP service uses a custom port, replace 443 with that specific port number. Ensure that both your on-premises and PDC firewalls allow traffic through the necessary ports. Additionally, confirm that the SOAP service is running properly on the PDC and that there are no network policies or security settings blocking the connection. If Telnet isn’t available, you can use alternatives like PowerShell’s Test-NetConnection or Netcat to test port connectivity. This approach should help identify and resolve any network or configuration issues causing the SOAP service failure.
