So here goes. I'm trying to implement GCM on my android app. The server part went good enough but as far as the client..
The client didn't seem to get the messages from the google server. I searched the web for this issue and I saw that it might be because port 5228 is blocked.
So I searched again how to find our whether thats the problem and I found this command which is suppose to tell me if the port is open or not:
telnet domain_name port_number
So I ran this command:
telnet localhost 5228
And sure enough I got this response:
Connecting To localhost...Could not open connection to the host, on port 5228: Connect failed
I didn't gave up and I tried to figure out how to open this port and I found windows manuel for this but still no go and the telnet command above brings the same results.
Now I gave up, if someone can assist or at least point to something wrong in what I did so far it would be great.
