HELP!!! Stratum connection failed: Could not resolve host

[chris47368]

Hey everyone this is my first post on here.I am trying to mine deeponion on x64 windows 10 using ccminer. I am using this command to try to mine:

ccminer-x64.exe -o stratum+tcp://onionminers.youngwebsolutions.com:17333 -u [my_worker_name] -p [worker_password]
pause

and everytime i open the .bat file i keep getting this:

[2018-04-13 21:24:12] Starting on stratum+tcp://onionminers.youngwebsolutions.com:17333

I have searched online for solutions but have not found alot that has been useful solving this problem.I have gone onto the mining pool website and followed all their instructions and set up my miners on my account....ect.

Any help would be very appreciated as i have spent hours trying to work around this issue.

Even though you are using the url provided on their site, try replacing onionminers with onionpool as described here: https://deeponion.org/community/threads/tutorial-deeponion-community-pool.1246/. Also, if you are mining on a GPU instead of an ASIC, try using port 17000 instead of 17333.  Otherwise, the difficulty level may be too high on the ASIC port for GPU mining once you get connected.

[chris47368]

Thanks HashAuger,I will look at the link you sent me and tell you how it goes shortly.I have tried switching the port to 17000 before since i too thought that might have been the issue,unfortunately same result Thanks for your time!!!

i have modified the command to the one suggested on the site:

ccminer.exe -a x13 -o stratum+tcp://onionpool.youngwebsolutions.com:17000 -u username.worker -p x -i 15 --cpu-priority=3

same issue unfortunately

The error says "cannot resolve host"

That is a DNS error of some sort almost every time.

Non-authoritative answer:
Name:    onionminers.youngwebsolutions.com
Address:  198.251.84.201

try stratum+tcp://198.251.84.201:17000 and see if that lets you connect. Also try an nslookup on your machine to verify DNS is functioning.

I tried both addresses on one of my machines and I could connect to onionminers, but not onionpool, so the pool is currently up and running.

I also tried the IP address instead of the host name and I can mine on the pool. Can you try to ping that IP address without that port number to see if you get a response?

I was able to get a ping from that ip adress strangely enough

That's weird. What version of CCMiner are you using?  I was using Tpruvot 2.2.5 for my tests.

[chris47368]

CCMINER 2.2.5.0 here too...

[HashAuger]

CCMINER 2.2.5.0 here too...

Just wondering. It seems more like a networking issue anyways.  I did notice that the error changed to "connection refused" when you used the IP address and not the host name. You might want to verify the format of your username and worker name.  I just used "-u testuser" and was able to connect.

Thanks for the time

[HashAuger]

I'm using just the -a -o and -u parameters.  Most pools don't use passwords, so might want to try removing it. I can connect to the pool, but I get a bunch of intermittent errors, including stratum authentication failed and the result won't validate on the CPU. But it is connecting and getting work.

[chris47368]

Thanks i will make sure i try that in the morning(since my pc is off now and about to go to bed) but i will let you know how it goes tomorrow.Thanks for the help you have given.

[JaredKaragen]

also, traceroute the ip for them.  see where in the hops your connection is lost.


it does state connection refused... seems as if the pool replied in a manner (weather that reply is simply a refusal for a TCP connection)

Not sure if this will help but it did for me. I recently had a network issue that caused a bad conndction to pools. It was down to Windoze10 updating while i was away. Whatever updates they did meant I then had to update the formware on my router. After that it has worked without issue. So try updating your router and see if that works.

yes, local routers carry a DNS cache; that can be a nuscence.  Same as your machine.

With windows 10, run a command prompt as admin, and type: "ipconfig /flushdns"  you should have your local machine's DNS resolver cache reset.


Second;  encryption relies on a proper date;  so make sure your system date is set properly (probably not it, but worth mentioning)
