I used claymore v11.0 and never had any issue on reconnecting when the internet rebooting or stop like the above said the claymore will restart in 20 seconds to reconnect.
This version works for me when mining ethereum but when overclocking it too high it crashes so just setup it with enough clock.
Yes but now I see what the problem is:
When claymore is trying to reconnect - its trying it and then crashing.. Is it possible to give it a command to close and reopen automatically?
