Cannot connect to my own dedicated Gmod server

Question

I can open the console in Gmod and use the command connect to try to join "localhost", "127.0.0.1", and "{my_ip_address}". However, these all show me a dialog box that says "Connection failed after 4 retries".

I have my server installed on Ubuntu 13.04. I wrote a little startup script to optionally update the server and then call this line:

./$GMOD_DIR/srcds_run -game garrysmod +maxplayers $MAX_PLAYERS +map $MAP

Where $GMOD_DIR is ${SERVER}/gmod/, $MAX_PLAYERS is 4, and $MAP is gm_construct.

It gives me this output:

Server will auto-restart if there is a crash.

I am mostly concerned with these lines:

Lua JIT is DISABLED!

I'm assuming this is some reference to Lua/Java Just In Time compiler

Nav File is wrong or something (4)

No idea what this is. Google didn't help very much.

Answer 1

The port could have changed to 27016 instead of the default 27015 since you are using 'connect' try going into 'Find Multiplayer Game' then into 'Local Area Network' and find your server there.

Answer 2

Add +ip 192.168.x.x to the line that starts the server in the script. Change 192.168.x.x to whatever the server's internal IP address is, as this is just an example. This can be found by typing ifconfig in Terminal. This shouldn't matter when trying to connect locally, but gmod might not like connections if a gateway isn't explicitly stated.

Answer 3

Your server has started normally. The Lua JIT interpreter might be disabled due to a missing dependency. Make sure that you have the Lua binary and devel packages off of apt-get.

I run a dedicated Garry's Mod server off of my local computer. In order to connect to my own server, I needed to use my external IP address to connect. Try connect <your external>:27015.

EDIT: The Lua JIT interpreter is disabled by default on purpose due to FPS issues. If you want to turn it on, add -withjit to your launch command.

Answer 4

Are you logged in as root? If not, try using sudo.

sudo ./$GMOD_DIR/srcds_run -game garrysmod +maxplayers $MAX_PLAYERS +map $MAP

Your worry about Lua JIT is probably nothing. What concerns me is this line: Unable to persist cache 'modelsounds.cache', check file permissions

Given that your script doesn't have permission to use the file, and that you "can't find" files in your cfg directory, leads me to believe you need to run this with advanced privileges.

This is analogous to running an app "As Administrator" in Windows.

Answer 5

You can also try disable firewall and test if this allows you to connect to server. If you haven't changed ports it should be this ones. 27015 and 27005 both TCP and UDP
