Tunnel not working and no "high quality" status anymore.

Recommended Posts

Hi,

We've started two tunnels almost since the beginning of cncnet. Now we've two issues with both:

1). There is a note for the server '91.121.146.57:51337', which says we need to contact you guys for information why the tunnel isn't working (v2). I did this previoustly and they told me to update the server. I did already since may (Linux), but it still gives the same error.  The IPTables are disabled either, to be sure that isn't the issue. Please, provide me some more info, why the server isn't working.

2). Our second tunnel '91.121.146.57:51338' hasn't got the 'Community tested high quality' status anymore. This server had it in the beginning (we runned two tunnels), but since we'd splitted the tunnels from one version only to one v2 and one v3 the status of this server is gone (the one which isn't working still has this status; which runs on the same server and same duration).

Hopefully you guys can provide me some more info what to do to get both issues to be fixed.

Thanks and regards,

Yorick

About the v2 tunnel I can't say much, you'll have to wait for @Grant, he might know more about the issue.

 

Servers lose the high quality status if they're unstable over a longer period of time (too high Jitter/Loss), I just checked your v3 server and it seems to be stable right now so I added it back to the high quality list. I will keep an eye on it and will let you know if there are some issues during the next days.

 

Thanks for providing the servers :)

Hi FunkyFr3sh,

Thanks for your reply.

(For @Grant ) Here some additional info regarding the v2 tunnel (Linux).

I've restarted the tunnel:

It seems like the GET request / heartbeat 'cncnet.org/master-announce?version=2&name=%5BEU%5D+Fast+Europe+Server+v2+-+www.FreeGameHosting.eu&password=0&port=51337&clients=0&maxclients=200' gets an ''OK' as response.

Hopefully this helps to solve the issue with this tunnel.

Thanks!

Kind regards,

Yorick

By the way, I've runned the server with exactly the same binary and only with a different port; and this server does works fine: 91.121.146.57:51339 . You guys may also set this server as good quality tunnel; but i also would like to know what is happening with the current server; to prevent I'd get this issue again. When can I expect a reply from the right person?

 

Thanks!

Not sure when grant is around, but if you played a test game and it works then I'm just gonna promote the new one quick if needed.

      Tunnel has never worked for me, the game client crashes after attempting to launch, returning back to the lobby and an error is shown in the chat saying there is an issue with the tunnel.
      Ive used others successfully (except for the lag given Im in Australia) and my own tunnel works.

      Hi,
      I'm the owner of the cncnet-server: 91.121.146.57:51337, and it shows that I've to contact you guys; so that's what I'm doing now! Could you please let me know why (the md5sums of the server file hasn't been changed; so no update i'd gues?!)?
      Thanks! 😃
      Kind regards,
      Yorick
