Hi there...

Using Claymore v11.7 and Simplemining:
-wd 1 -r 0 -epool europe.ethash-hub.miningpoolhub.com:17020 -ewal ChrisWSM.$rigName -eworker ChrisWSM.$rigName -esm 2 -epsw x -estale 0 -allpools 1 -allcoins 1 -ejobtimeout 2

A few people are talking about a drop in hash rate, and I have also dropped hash rate, but I know why...

I've a situation where I have 8 x 12 GPU rigs, all mining to europe.ethash-hub.miningpoolhub.com:17020 and have been for a few months, without issue. Yesterday, I started to see every rig showing ETH: xxxxxxxx - SHARE FOUND - (GPU x) but not ETH: Share accepted (xx ms)! I also noticed that I was not seeing ETH: xxxxx - New job from europe.ethash-hub.miningpoolhub.com:17020

-ejobtimeout would kick in after 10 mins and the rig would reconnect and work fine. Having checked my Claymore log file, this is happening at random times, at least 2 times per hour. I have dropped -ejobtimeout to 2 mins, and it's now happening at least 5 times per hour.
If it was a router rules issue, it would fail or pass, not go some mins and then fail.

Any thoughts or help would be appreciated.
