Hi, 
  
I'm having the same problem :-( 
  
More information : 
- the same on Windows 8 and Windows 8.1 
- no connection is made on the server (verified with Wireshark and IIS logs) 
- pcmonitor.mydomain.tld pointing to the internal IP address (tried A record, cname record and even hosts file) 
- no problem to acces by web interface or with the agent 
  
This problem is very important for me as the main function I'm looking for is Windows 8 app ... 
  
I'm available for any debugging help. 
  
Best regards
