Hi th00ber, I'm stumped with this one:

After PhoenixMiner updated their log to the correct time, I've set up 15 rigs just fine....

... except for ONE rig.  I've got the dreaded "miner not found/not hashing" error:

[INFO] Sending mining informations to Monitorig server
[ERROR] The miner is not running or is not hashing
{
  hash: 0
  share: 0
  infos: 00:00:00.000 -> main GPUs: 1: 0.000 MH/s (0)
}
[SUCCES] Succesfully updated

The checklist I've done:
- log file is working fine, the clock times match
- I've re-downloaded/reinstalled both Monitorig and PhoenixMiner
- restarted the rig a few times
- let the rig run overnight (hoping it'd catch up eventually), no luck
- I even let Windows Firewall communicate freely both .exe for PhoenixMiner and Monitorig

Any other suggestions?  Like I've mentioned, I've successfully done 15 rigs, so I know for sure it **should** work:
- the non-working rig shares the same IP (location, internet connection) as 4 others that work

The only quirk: this non-working rig has only one GPU, the rest have multi-GPU.
