NuBot / stream.tradingbot.nu:5556

Development Issue reports
#1

Is there a NuBot operator around?
I pm’ed @desrever, but two days ago he told us about

I recognized that the liquidity information was not being broadcast properly from NuBot.
I started nud with no effect.
Then I started NuBot.
The result: NuBot doesn’t start.

The error message reads

12:47:38.106 [main] ERROR - could not launch bot com.nubits.nubot.bot.NuBotRunException: java.lang.IllegalArgumentException: java.net.UnknownHostException: stream.tradingbot.nu: unknown error [c.n.n.l.MainLaunch:173]

nud seems to run properly and with the right ports:

netstat -lntu
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 0.0.0.0:9090            0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:9091            0.0.0.0:*               LISTEN

Needless to say that I didn’t change the rpcuser or the rpcpassword of nud - it still is the same in ~/.nu/nu.conf and the NuBot config file.

For the record: name resolution for stream.tradingbot.nu doesn’t work and I guess the NuBot malfunction is related to that.

The example config on bitbucket uses a different port, but I was told that 5556 is right. So my NuBot config file contains

stream.tradingbot.nu:5556

Is anybody able to tell me the correct streaming server settings?

#2

Hi @masterOfDisaster I will look into it, in the meantime simply set bypassStreaming : true

#3

Thank you for your reply and your extraordinary level of support - even if you are away from computers!
I was hesitant about changing that parameter.
As far as I understand the streaming server is required for price discovery, no?

I set it to bypassStreaming : true following your recommendation.
NuBot on modPuddle is up again.

#4

I’ve found what the problem is : I didn’t pay the renewal of the domain name tradingbot.nu … Doing it now. Sorry.

Its not strictly required, but it facilitate a smooth and sync pricing with multiple operators… NuBot is able to work without it autonomously and if you set multiplecustodian to true will use a list of NTP servers to sync its clock with others, and hard reset walls every three minutes.

PS: starting tomorrow I will slowly roll back into Nu development activities. Forgive my absence .

#5

Back, you can try to turn the bypass off !

#6

Bypass is off. NuBot is running. Issue resolved!

#7

@desrever,
is there trouble with the stream server (“streamingServer” : “stream.tradingbot.nu:5556”,) or is the problem at my end?

I just restarted the service, could you try again?

Good find, need to investigate this . Thanks
