ECONNREFUSED error

So after changing my Java settings Change Runnable Jar: to point to spigot.jar, I started the server.
I am getting the above error string.

The server DOES appear to be up and accepting connections though. The number of players does NOT seem to update in the UI.

This means that the minecraft server isn’t responding to the ping request from the web-ui. This happens every now and then with various old versions of spigot, bukkit, and forge. It is non-critical, but topically annoying. If you can let me know what minecraft server you’re running (specifically what version, and maybe a URL) I can see what ping protocol that is running and try to get that fixed.

thanks

eeclarkjr · August 14, 2015, 5:40pm

I installed1.8.8

Ok… getting the same thing with 1.8.8.

CraftBukkit version git-Spigot-fdc1440-53fac9f (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)

That is not old. Hopefully you can find the issue.
If there is anything else I can do to help, please let me know.
Thanks

hexparrot · August 14, 2015, 8:54pm

Did you just download a normal jarfile from http://getspigot.org? Or did you build it yourself?

I basically want to make sure I’m testing against the same copy you are.

eeclarkjr · August 15, 2015, 1:38am

I followed the instructions according to the spigot site in which you use build tools to build the .jar file. https://www.spigotmc.org/threads/buildtools-updates-information.42865/

eeclarkjr · August 15, 2015, 1:43am

To make things even easier…I went ahead and used the spigot_server.jar from the http://getspigot.org site. That way you can test “apples to apples”.

[20:42:37] [Server thread/INFO]: This server is running CraftBukkit version git-Spigot-fdc1440-53fac9f (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)

This appears to be the same version number that I had built using build tools, but at least now you know it is not a ‘build’ issue with my jar.

I am still getting the same ECONNREFUSED error.

hexparrot · August 15, 2015, 2:32am

ECONNREFUSED is the error when MineOS tries to poll the server and the server doesn’t understand the ping request.

http://wiki.vg/Protocol_History#1.8

1.6.x
1.6.1: Protocol version is now 73. Packet 0xFA is sent after packet 0xFE with additional data
1.6: Protocol version is now 72. Changed Open Window packet, added two inventory types

However, according to this same page, chronologically the most recent updates (1.8+) seem to change the protocol version:

15w32a
Protocol Version is now 52
15w31a/b/c
Protocol Version is now 51

Can’t really tell why it would be 51,52, considering that that is a version used…back in 1.5.x.
Since almost all servers now are between 1.5.x and 1.8.x, servicing only protocol version 73 seemed to fit the bill just fine. vanilla 1.8.8 seems to work just fine, too…the only issue arising for your spigot/craftbukkit build.

I don’t really know what’s going on here, or why it seems like a regression in protocol, but I’ll hopefully be able to look at it soon.

eeclarkjr · August 15, 2015, 2:59am

Hey thanks for getting back to me on it. I appreciate all the hard work you do as a developer. I know it is sometimes a thankless effort, so hopefully I can mitigate that to some degree.

Thanks
Ed

Unable to reproduce this issue while trying out the same getspigot build:

I’m using it entirely without plugins, though. Are you using any?

eeclarkjr · August 15, 2015, 10:30pm

Yes. Using many plugins.

ElPres · August 16, 2015, 12:12pm

Are you sure that the startup has finished?

eeclarkjr · August 16, 2015, 1:51pm

yes i am sure it has

hexparrot · August 18, 2015, 11:16pm

If you’d like to provide me personally with an archive of your server, it would make it easier for me to test this. As is, the standard, no-plugin spigot download works without issue. I do, of course, want to handle all cases–and most cases will involve plugins.

Perhaps like Forge servers, one of these plugins is modifying the self-reporting API version (and making it older than the 1.8.8 version that is expected). I’d need to reproduce the issue to fix it, and I’d be happy to do that with a known-failing copy of your server.

If you choose to, feel free to crop out the /world data (to save space/transmit time) and the spigot jar (to keep yourself on the legal side of things) and I can take a look at what’s going on.

eeclarkjr · August 18, 2015, 11:46pm

Sure thing. I can zip the archive and strip out the items mentioned. How should I send it?

hexparrot · August 18, 2015, 11:53pm

If all the world data is gone, it might be small enough to email, but if not, then if you have a dropbox or equivalent?

eeclarkjr · August 18, 2015, 11:55pm

39 MB - I will locate a dropbox and post. I will email you the invite from Dropbox.

I put it in a .tar file.

Upload is complete.

If you have any issues retrieving via dropbox, let me know and I will email it to you directly.
Thanks

hexparrot · August 19, 2015, 12:22am

Hrm… Unable to reproduce:

Same 1/20 results from spigot_server.jar and craftbukkit_server.jar

Out of curiosity, if you clear out your MOTD, does it fix anything? It worked for me with the MOTD intact, but this was the solution for many forge servers in the past. Also, have you updated your webui to the most recent commit too? (you’re current if you’re on MineOS Turnkey)

eeclarkjr · August 19, 2015, 12:48am

Removed MOTD – no change
Running MineOS 1.2.2

Also did the following as root (via sudo):

cd /usr/games/minecraft
git fetch
git reset --hard origin/master
npm install --all

with one user logged in…still no update to players online count.

I also went ahead and downloaded the spigot_server.jar again from http://getspigot.org. Did a Stop/Start and joined the server…still no ping and no player count.

I did notice that I have to keep setting the “Change Runnable Jar:” to spigot_server.jar. Not sure if that matters.

Any chance I have some permissions wrong in the /usr/games/minecraft folder? Is node_modules supposed to be owned by root?
