Not working, miner disconected 4 hour ago

[vsystech]

Dear Developer, i have a problem with stratum script. running 8 hour without problem. after i'm looking some "unauthencited" try restart the proxy, stop start. but hashrate drop down. miners not reconnect.

restart the server, 4 hour ago only looking this logs.

http://prntscr.com/hor9ms

[vsystech]

Using the latest version: {"version":"2.6.4"}

starting with coin-hive-stratum 8892 --host=pool.supportxmr.com --port=3333 command

[cazala]

are you using CoinHive.Anonymous or CoinHive.User to instantiate your miners?

[vsystech]

CoinHive.User(with wallet address, and worker name) but i'm said the proxy is worked to 8 - 9 hour. before have a first problem. and when restart the proxy. get the connect disconnect error. and no hash speed, no shares)

http://prntscr.com/hor9ms

[cazala]

are you running with pm2?

[vsystech]

no, start with coin-hive-stratum 8892 --host=pool.supportxmr.com --port=3333

maybe you have a skype ?

[vsystech]

i'm start proxy on other server, and looking few logs.

http://prntscr.com/hou90e

[vsystech]

Now working again the server, http://prntscr.com/hou9m7

but elapsed 6 hour. and no hashes. os share submit. only connect - disconnect.

[vsystech]

Don't get reply but i have other problem. i have a 16 gb ram dedicated server, running the script but after 1500~ connection not accept more. only write 0 hashes per sec. why ? please help me solve this problem.

Yesterday I also started to have problem with that proxy. Almost all the time "miner disconnected" information. I also noticed big decrease of efficiency. I am running proxy with pm2 and in rush hour I have more than 10k miners.

[cazala]

does it go back to normal if you reset it (stop/start) ? 10k miner is a heavy load, how many instances of the proxy are you running? you can set the number of instances using the -i flag, like pm2 start proxy -i 4

[vsystech]

not back to normal started the server but wait 4-5 hour to working again and send shares. . if try start with pm not starting and get error if check pm monit.

[vsystech]

currently running the server try connect from browser miner. 10/7 try connect to server but Core: 2 Hashes/s : 0 Total Hashes/s : 0 Total Accept : 0

and not starting the miner.

[cazala]

it appears that this starts to happen after an Unauthorized occurs. Something similar has been reported in #105, but I don't know if this is a pool issue (like a pool ban) in that case restarting the server won't help if the IP was blacklisted or something (maybe due to too many connections). Once I had my monero address swiped by a proxy because I had to many connections. If this happens again I encourage you to try a different monero address or mining on a different pool, like https://moneroocean.stream/ (gulf.moneroocean.stream:80 has a difficulty of only 100) and see if this still happens. I still don't know what causes that Unauthorized but I want to figure out if the decrement in hashrate that comes afterwards is a pool ban or an issue with the proxy.

[cazala]

Something that helps to mitigate the load is having more than one proxy running (like one on port 9000, another on port 9001 and so forth). then you can add several proxies in the WEBSOCKET_SHARDS array:

CoinHive.CONFIG.WEBSOCKET_SHARDS = [["ws://my-proxy.com:9000", "ws://my-proxy.com:9001", ...]];

[cazala]

Apparently this is also an issue that happens when using CoinHive.User and not CoinHive.Anonymous... do you know how many different "users" do you have?

[vsystech]

yes, currently 6 different user. sorry user is fix, my wallet address but use 6-7 worker.

[vsystech]

i'm start proxy on different port.

{ "miners": 2709, "connections": 1 }

{ "miners": 140, "connections": 1 }

when try connect to first, not start hashing.

the second start immediatelly, so not problem with my server resources. but i don't understand. maybe limit on port connection or what ?

[vsystech]

and i have a some problem with x25 coinhive stratum. after 1000-1500 miner not connect new miners 0 hash 0 share. currently i use 4 proxy with 3 different server. and i think is suck :D

[cazala]

mm yes, that's not got. the proxy should have 1 connection every 100 miners, and I can see that your proxy has 2709 using the same single TCP connection... are you running using the CLI? try this:

coin-hive-stratum 8892 --host=HOST --port=PORT --miners-per-connection=1

[vsystech]

i'm try nothing changes.

{ "miners": 191, "connections": 1 }

[cazala]

sorry! my bad, the flag is --max-miners-per-connection=1

[vsystech]

wooow, that is a new error on dash.

http://prntscr.com/hp4nlh

maybe to many connection when restart 2700 + 300 connection to supportxmr :D

[cazala]

okay, how are your /stats now?

[cazala]

that's probably because of too many connections now.

[vsystech]

{ "miners": 838, "connections": 849 }

{ "miners": 330, "connections": 341 }

[cazala]

yea, that's why. what if you try --max-miners-per-connection=200 ? It should be 100 by default but for some reason your connections where stuck on a single one...

[vsystech]

wooow, i think now better the situation i get more +8kh/s speed.

so use 200 on correct value ?

[cazala]

yes so far people have reported that 100-250 miners per connection is working fine. I don't know why your proxy was stuck on a single connection... do you remember if your /stats have always shown a single connection?

My assumption is that the proxy had always a single TCP connection and at some point there were too many miners using it and messages started to drop. The proxy doesn't purge connections so I don't think that it went from many connections to a single one, but instead it started with a single one and never created more.

Please let me know if this starts happening again :)

[vsystech]

yes always 1 connection. on three machine :) i'm try install now to 4th machine this script but when run install.sh get a problem.

installed other (x25) script. how can i remove ? maybe this is the problem.

[cazala]

mm did you clone this repo and then run the curl inside that repo? The error you are getting is becuase you are doing an npm install coin-hive-stratum on a directory that has a package.json with that name already.

Make sure you run the installation curl from ~/

[cazala]

so you still have a single tcp connection per proxy?

[vsystech]

yes, but now setup 100 and working as good.

{ "miners": 803, "connections": 9 }

{ "miners": 607, "connections": 7 }

{ "miners": 891, "connections": 10 }

after restart not reconnect all miner.

[cazala]

ahh okay, so when you passed the --max-miners-per-connection=100 it worked. And before that you were running just coin-hive-stratum 8892 --host=pool.supportxmr.com --port=3333 without the flag, right?

It's so weird that your proxy was stuck in a single connection... anyway, I just released a patch (v2.6.5) that logs the max miners per connection when the proxy is started, to make it easier to figure out when this is the problem.

[vsystech]

Okay :) have a great job and thanks your help!

[cazala]

no problem!

[vsystech]

Sorry to bother you again :( how can i calculate earning to workers ? i'm working on this problem 2 days ago :( maybe you have a great idea ?
