I'm having problems connecting to the US scrypt URL. I'm using the latest (as of a week or two ago) bfgminer under Minera with a Zeus Thunder X3.
I can connect fine to the EU server:
[2015-08-28 07:33:23] Pool 4 stratum+tcp://scrypt.eu.nicehash.com:3333/#xnsub alive
But not the US server:
[2015-08-28 07:33:53] Testing pool stratum+tcp://scrypt.usa.nicehash.com:3333/#xnsub
[2015-08-28 07:33:53] Closing socket for stratum pool 3
The rig is in Campbell California, so it's right around the corner from San Jose.
I've tried disabling the profitability option in the password field. I also tried with and without "#xnsub" (originally the problem was without this option). Neither change helps.
I've got two other rigs in the same LAN running an older cpuminer and old Minera with gridseed 5 chips that can connect to scrypt.usa.nicehash.com with no problem. All three rigs are behind a firewall, so they appear to the outside world to be from a single WAN address.
Here's my command line for the problematic rig:
/var/www/minera/minera-bin/bfgminer --scrypt -S zus:all --set zus:chips=128 --set zus:clock=332 --scan-time=1 -c /var/www/minera/conf/miner_conf.json
Here's the excerpt from the json config file for the US pool (with the receive address and worker name removed):
{
"url": "stratum+tcp:\/\/scrypt.usa.nicehash.com:3333\/#xnsub",
"user": "HIDDEN_ADDRESS.WORKER",
"pass": "x"
},
Originally I thought it might be a routing problem, but then why do the other rigs in the same LAN connect to the US server fine? Then I thought maybe it's a bfgminer problem, but why would it connect to the EU server and not the US server?
I've got several pools configured on the problematic rig and it can connect to all of them except the Nicehash US server.
Any ideas?
