Can't connect to Linux VPS based server

[0cyris]

Server is running CentOS 7.2 x64 hosted by Digital Ocean have also tried Debian and Ubuntu.

Every time someone tries to connect it fails with "onP2PSessionConnectFail" even without a firewall of any kind.

 

I've tried just about everything I can think of and haven't been able to find anyone else with a working solution.

Have you disabled UPnP in servertest.ini, as well as ForceUPnP? Chances are they don't support it.

[0cyris]

Just tried disabling them with the same result.

 

The only other thing I've notice is in netstat with the address it's sending connections from when someone attempts to connect.  

netstat -atunp | grep Project

Does it create some kind of tunnel?  I know I don't have any interface up with an IP of 10.13.0.5 and since it's a non-routable address that's the only thing I can think of.

[0cyris]

Setup a node on linode and it works fine so it must be something specific to Digital Ocean.  I'll try contacting them since it means I have to use their competitor and post if I get an answer.

[0cyris]

The only thing Digital Ocean was able to offer was it might be picking up the anchor IP use for their floating IP feature.  Doesn't seem like much can be done without being able to configure IP address binding.

 

As I said before Linode works great and has similar pricing so that my solution for now.

[EnigmaGrey]

Odd, as Kirrus was running a PZ co-op server through Digital Ocean successfully. I wonder if he had to do anything special to set it up.

 

Not sure on the IP binding . . . I -think- EasyPickins added a flag for it, but will have to check.

 

Yep. e.x. zombie.network.GameServer -ip 127.0.0.1

Thanks 0cyris! It was the anchor ip. I've been troubleshooting this for hours, but deleting the anchor ip fixed it.

1. Find out your server's anchor ip

   curl -s http://169.254.169.254/metadata/v1/interfaces/public/0/anchor_ipv4/address
   

2. Confirm that the anchor ip exists:

   ip addr list
   

3. Delete your anchor ip

   ip addr delete <anchor ip + mask> dev eth0
   
   example: ip addr delete 10.46.0.6/16 dev eth0
   

4. Confirm that anchor ip is deleted

   ip addr list
   

Should be good to go after that!
