It is not possible to login into Parallels Power Panel (PPP). An error occurs on applying IIS certificate bindings for HTTPS:
A specified logon session does not exist. It may already have been terminated.(Exception from HRESULT:0x80070520)
The same error may occur on PVA Agent (re)installation:
SetWebSiteBindings at .\iis_configuration.cpp:168 [ERROR] IADs::SetInfo failure 0x80070520 A specified logon session does not exist. It may already have been terminated.
The new CA certificate cannot be applied.
To resolve this issue:
Open Internet Information Services (IIS) Manager on the server home page and select Server Certificates
- Delete all PVA Power Panel self-signed SSL certificates and DO NOT DELETE the CA root certificate issued to the server itself
Reconfigure Parallels Power Panel:
C:\Program Files (x86)\Parallels\Parallels Virtual Automation\Power Panel\bin\pp-config.exe postinstall
- In IIS manager, open the PVA Power Panel Web Site page and click Bindings on the right
- Choose HTTPS, press Edit, select one of the available SSL certificates, and press OK.
