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

[Yorick]

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.

Yes, please. I will keep the original one online; so grant can check what the issues are with that tunnel.

Thanks!

Thanks. BTW. It surprises me how mutch people are currently using our tunnels (v2:  47 - v3: 19). Is there a way to become a Official Tunnel?

Could you reply on my last question?

 

Thanks!

[FunkyFr3sh]

Sorry missed your post.

I'm not even sure if we're going to keep the official tunnel thing since it has no advantages at all, it even has some disadvantages (broken official tunnels can't be disabled and people fail to start games...).

Currently all official tunnels (besides one) are managed by us, that means we got full access to the server and in case a tunnel fails we can ssh in and fix it. (This is necessary, see above, they can't be disabled...). 

So yeah, it's not really any useful and just gives us headache and problems

Thanks! Could you please give the status to the new tunnels i creeated on the IP-address 178.32.35.210? We want to remove the tunnels from the current IP-address; because the tunnel causes some issues for other proccesses.

Let me know!

Both are working fine, both got the high quality status now
