My Device cannot connect to Serviio server

Dear All,
I have successfully installed serviio 1.6.1 on my windows 8 PC. The server is up and running and the Library is in sync with the shared folder.

Both my devices Sony Bravia Bravia KDL-48W700C TV and Samsung Galaxy S4 phone lists the Serviio server in Media server list and Nearby Devices respectively.

However when I click on Serviio server on my Sony TV I am getting "Connecting to the server. Please wait" and on my Samsung S4 phone i get "Processing" for infinite period of time.

I have both TCP port 8895 and UDP 1900 opened in my firewall. I have Mcafee Antivirus installed in my PC where Serviio Media Server is running but it is not blocked.

I have restarted the Serviio services and my PC several times but the problem is not resolved.

I even downgraded to Serviio 1.4.1.2 but the result is still the same.

Can someone help me to resolve this issue?

Thank You
