ConnectionRefusedError: [Errno 111] Connection refused

I'm trying to get this to function on a minimal headless Centos 7 server, but it seems to fail in various ways. ConnectionRefusedError on initial start up with no settings.conf. If I run nuxhashd again, putting in my info, it just hangs, CPU at 100%. I've tried various arguments, -v and --show-mining, but I can't figure out why the program fails. (I've run Claymore ETH miner on this before without an issue, and now I want to try other algorithms)

Since Centos 7 only has python 2.7, I had to install python 3.6.3 with a Software Collection (https://linuxize.com/post/how-to-install-python-3-on-centos-7/), hopefully that isn't causing an issue. $ python -V Python 3.6.3

After looking through the Issues, I added a settings.conf with a [nicehash] section. I ran nuxhashd a few more times, failing or hanging. Then I checked my settings.conf and nuxhashd had written a few more sections: (I added the listen address and port) My .config/nuxhash/settings.conf: `[nicehash] wallet = 3QtrjJpp9HYcgkJf7omZFMJZ6s3ELuxbot workername = nuxhash region = usa

[switching] interval = 60 threshold = 0.1

[gui] units = mBTC

[donate] optout = False

[excavator_miner] listen = 127.0.0.1:4000 args =`

I don't know if nicehash broke something on their end, but I can't get nicehash to mine on my setup. Any help?

Apologies for the delay. My hunch is that excavator is failing to start. Run ~/.config/nuxhash/excavator/excavator -i 127.0.0.1 -p 5001 in a terminal and see what happens.

Problem was on my end. I was using outdated Nvidia drivers (390) somehow on my CentOS install. When I ran just excavator like you said, it just said "couldn't find any devices" and quit. Some googling led my to believe it was an openCL issue or outdated issue. After I did a full "yum upgrade" of my server, having seen old drivers and kernel present, excavator now works great! I upgraded to nvidia-x11-drv-418.56-1.el7_6.elrepo.x86_64 and kmod-nvidia-418.56-1.el7_6.elrepo.x86_64, FYI.

Glad to hear it.
