If this topic is already somewhere else please point me to it, thanks.

      I am running bitcoin server 19 with a couple miners it works great but occasionally the miners say they cannot connect to bitcoin RPC even though the server looks like it is working fine.  When I restart the bitcoin program every works just fine again. What is going on?

P.S. I do NOT restart the miners when I restart the bitcoin server.
P.P.S. This problem occurred my previous bitcoin server as well.


I downloaded the new bitcoin version 3.20 and the glitches stopped.
