Updated the pool diff, try now.
Okay, I restarted the miner about 15 minutes ago and difficulty once again climbed up to 100001; I restarted it just now - difficulty started at 2000 on port 3333 - so we'll see (lol - already up to 16000 as I type this).
We are continuously monitoring the DERO NW and pool but we didn't find any ping loss in last 2 days. if CPU overload is the case we will start logging our CPU 24 hrs and check for anomaly.
I can assure you it wasn't my internet connection because I have 3 separate computers mining right now and yours was the only one that kicked off. I wish I had taken a screen shot of what xmr-stak reported as the problem, but I have retries set to a 30 second interval with 3 max and it basically gave up. I've since changed it to 5 retries with 60s between them.
