Symptoms
- I cannot register/activate Parallels Remote Application Server.
- I am getting an error: Failed to communicate with Parallels Authentication Server
Cause
Connectivity to the remote server is blocked.
Resolution
Please ensure that from Server where Parallels Remote Application Server Master Publishing Agent is installed you can connect to:
- https://ras.parallels.com
- https://account.parallels.com
- https://license.parallels.com
- https://s.parallels.com
If your firewall solution doesn't allow whitelisting FQDNs, please whitelist the subnets listed here.
The following Telnet test can be performed to ensure connectivity:
telnet ras.parallels.com 443
telnet account.parallels.com 443
telnet license.parallels.com 443
telnet s.parallels.com 443
Or using PowerShell:
Test-NetConnection ras.parallels.com -Port 443
Test-NetConnection account.parallels.com -Port 443
Test-NetConnection license.parallels.com -Port 443
Test-NetConnection s.parallels.com -Port 443
