The common issue’s with rejected shares.

Hello RavenMiners!

I would like to know a couple of common issues when you mining RVN -> getting rejected shares. Recently after running my rig for a week, now suddenly I had 29 rejected shares in an hour!?

What can be the issue related to rejected shares, is it on my end, or is the network doing something wrong? Also, I was checking the OS today and suddenly my rig crashed and rebooted on the NBminer software in 10 seconds.

Excuse me for my language it is not my main to write properly.

I have switched from ETH -> RVN last week and it went all smooth till today.
