Server refuses to be accessible on port 5400 (Beta 4.1)

[Teppy]

Hey guys,

 

I had got 3.1 running successfully on my linux server (centOS7)

 

However, with the new one, no matter if I open the port or anything, I get UPnP Service Initialization Failed followed by "It appears that UPnP Failed. You might need to enable UPNP on your router or manually port forward to allow connections to your server." and sure enough I can't connect. Any advice?

UPnP can communicate with your router to open ports. In this case it doesn't seem like you have a router firewall to deal with so you can ignore all UPnP messages. (That really only benefits home users)

 

That said you still have IPTABLES or some other firewall on the server itself you will need to work though just like on Windows you'd allow Intersect to be communicated with through Windows firewall.

That might give you a hint at where to start.

 

Edit: Please note we are now using UDP instead of TCP when dealing with port forwarding.

I even just tried manually changing the used port back to 4500 (which worked before) and it still doesn't work.

firewall doesn't seem to run on my server, but I did do iptables -I INPUT -p tcp --dport 5400 -j ACCEPT

 

Still no luck

As of Beta 4 we are using UDP instead of TCP

I might just reformat the server and retry,a not sure why I can't get this to work, even using UDP. Will post back here in case you have any advice

Look up how to insert your new rule into the top of your IPTABLES list. It does you no good if you add the rule at the bottom to accept if there is a rule above it saying to deny.
