2 days ago I updated from 6.5.3 to 6.6.0. After the reboot I tried copying some files to the share and nothing will copy. I get an unexpected network error. I downgraded back to 6.5.3 and I still have the same problem. I didn't have this problem before the update. I have another unraid setup for a second backup that I had not updated yet. So far I've been able to read from the one I updated and copy over the the other one. The latest logs I have are below. There is one error at the top after restarting the array.  I was trying to copy a file to the array a couple minutes after the last log entry. I have it set with a static ipv4 address.

I've been able to copy some stuff but it will sporadically stop transferring. I connected a monitor to it and noticed the monitor blinks off for a second and I've seen transfers stop at that time.
