Im running 2 hp servers for plotting and i have 10 plots one 1st server and 18 plots on 2nd server but, no one is sync always yellow.
I have sync time on both machines.
I define on router
port 8445 → 8444 for 1st server
port 8444 → 8444 for 2nd server
I have test ports from Open Port Check Tool - Test Port Forwarding on Your Router
and both are open.
