Cannot connect to my own mumble server using external ip

Question

I can connect to my mumble server through my local (Wireless LAN IPv4) ip: 192.168.0.15, but I cannot connect using the ip taken from this website: http://www.whatismyip.com/.

I have forwarded 192.168.0.15 at port 64738 on my modem, both TCP and UDP. And I still cannot connect. I have not changed any settings in mumble or murmur, they are all at their defaults, but I have registered myself as a user while connected via local ip.

This is the error I get with mumble, before I join using my local ip (I've censored my external ip with x's):

 [10:54:23 AM] Welcome to Mumble.
 [10:54:33 AM] Connecting to server 99.236.xxx.xx.

 [10:56:52 AM] Connecting to server 192.168.0.15.
 [10:56:53 AM] Connected.

And here is the murmur log:

I am using windows 8.1 and have avast! antivirus.

edit: I have used canyouseeme.org to determine that port 64738 is in fact open.

Solution

Here's some steps you might want to double check. Networking, port forwarding, and the like can be somewhat tedious at times.

1. Double check that the port is open. Try using this open port checker just to confirm. I've seen weird situations where it's not possible to connect to a server running on the same computer using the external IP. Get another computer involved.
2. If the previous step fails and the instance of the Mumble server is binding correctly, it's probably an issue with port forwarding or a firewall. If this is the case, the first thing I would do is disable Avast and remove the Windows firewall (or any other security measures). Again, this is not safe permanent option, but good for narrowing down the issue.

Edit: Since the port is open according to the open port checker, try connecting from another computer. Does it work?

I don't have another computer I can connect using local ip currently, I can't imagine my friend would be able to connect since I can't even connect using my external ip. I had a friend try to connect anyway, no data was received.

Wait, I did get this around the time my friend said he tried to join, but he told me no data was recieved: <W>2014-11-26 13:59:15.587 1 => <15:(-1)> New connection: 69.17.141.122:55341 <W>2014-11-26 13:59:15.700 1 => <15:(-1)> Connection closed: Error during SSL handshake: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number [13] However when I try to join my own server using my external ip, the log shows nothing.

[Billy Butts]

Well it seems that my other friend can join. But, is there any particular reason I cannot join using my own external ip? I assumed it meant my friends couldn't join, but as far as I can tell everything is fine. Thanks anyways.
