millititus Posted March 13, 2022 Share Posted March 13, 2022 I recently had to format my server box, and I saved all the world files and configuration files. I had a successful server running about three weeks ago when my server died. I was able to get it back up and running after formatting, and I reinstalled 7dtd dedicated using steamcmd like I had set it up before. I thought I had everything set up properly, but now players cannot see my server in the game list, nor connect to it by IP. I can join the server using the local address, but anyone outside of my network cannot. The really strange thing is when I connect to the server, others can too. They can even see it in the server list. I don't know what is wrong, when they try to connect by IP address, the connection times out. Any suggestions? I can post my configuration if that helps.

Maybe your internal ip changed when you rebuilt the server, so now your natting is going to the wrong address. Or, you're using a different port?

millititus Posted March 14, 2022 Author Share Posted March 14, 2022 I am using the default ports, which I have set up in my router, and the internal IP is static, so that hasn't changed. Link to comment Share on other sites More sharing options...
SylenThunder Posted March 14, 2022 Share Posted March 14, 2022 Logs and details on your setup would be quite useful. Link to comment Share on other sites More sharing options...
millititus Posted March 14, 2022 Author Share Posted March 14, 2022 This is my latest log, again I am able to log in locally, but others cannot join. They could when I had steamnetworking enabled, but only when I was present on the server. https://pastebin.com/aJa1KCSi Here is my config file. https://pastebin.com/FVQ7up68 Link to comment Share on other sites More sharing options...

Need to be in both your router and Windows firewall. Also, AV can cause this so it's recomended to add an exclusion in Defender for the game and save folders. Also, since you're password protected, you could disable EAC. Link to comment Share on other sites More sharing options...
millititus Posted March 14, 2022 Author Share Posted March 14, 2022 Ok, I plan on trying to factory reset my router and rebuild the routing table. I will update with results afterwards. Link to comment Share on other sites More sharing options...
millititus Posted March 15, 2022 Author Share Posted March 15, 2022 I did factory reset my router, and added TCP 26900, & UDP 26900 through 26903 to my port forwarding table. Users are still unable to see my server. Any more thoughts guys? I added the rules to windows firewall as well. Link to comment Share on other sites More sharing options...
SylenThunder Posted March 15, 2022 Share Posted March 15, 2022 Check that you don't have CG-NAT. That has been a really common issue the past couple of years. Link to comment Share on other sites More sharing options...
millititus Posted March 16, 2022 Author Share Posted March 16, 2022 How can I check to see if I have that? Also the real strange part is that its a recent issue. I have had a server up and running up through mid-February. It only recently stopped working when I formatted my server. But I figured factory resetting the router would remove any previous routing issues. There are only 7days port forwarding rules in there now. I just found an article about CGNAT and I am checking now. As far as I can tell, I do not have CG-NAT. I checked my external IP address at whatsmyip.org is the same address as my router reports.

millititus Posted March 16, 2022 Author Share Posted March 16, 2022 I also verified using an online port checking tool that 26900 is open when I have the server running. Interestingly, 26901, 26902, and 26903 are reporting that they are closed, even though I have the rule set up in my routing table. Is this an issue?

I have heard multiple times of this happening with various routers. My suggestion is to check forums for your brand of router or even the forums of dslreports.com. Maybe tell us make/model of the router in case someone here has experience with it. Link to comment Share on other sites More sharing options...
millititus Posted March 17, 2022 Author Share Posted March 17, 2022 Its the original Google Mesh Wifi. Not the Nest wifi, but the old one. Link to comment Share on other sites More sharing options...
Star69 Posted March 17, 2022 Share Posted March 17, 2022 (edited) A quick google search showed a whole bunch of folks have problems with Google Mesh and port forwarding. 1) Some say disable ipv6, forward your ports then enable ipv6 when done. 2) Another says to give your server a reservation on the dhcp table then forward ports. This recommendation actually came from Google Support so I'd try this. For some reason with Google the forwarded ports are based on device rather than IP address like many others do. 3) Update your firmware, restart the router after each port has been forwarded 4) set router to bridge mode 5) Make sure that you aren't double-natted, that your modem has a built in router on top of your Google Mesh router Edited March 17, 2022 by Star69 (see edit history) 1 Link to comment Share on other sites More sharing options...
