Error content:
Couldn't connect to a devfee pol for a long time
Please check you firewall/antivirus is not blocking connections
Mining will be paused...
Multiple devices randomly report errors, the restart of miners is normal, the firewall is not disabled/need to open what ports?
This does not tell us much.
Which OS?
Commands used?
ISP issues?
hiveos dnx+rxd+zil Not all miners report errors at the same time, but some miners report errors at any time. After the background checks the error, miners will reconnect to devfee pol a long time later

I must admit I have never set firewall ports/rules when mining on Debian testing/trixie and touch wood never had any issues like you have.
Maybe some OC clocks not playing well as over time videocards do degrade a bit what is effecting some of your videocards.
Take it you are using the latest HiveOS, otherwise try updating it as maybe some firewall settings might have changed which are updated in the meantime.
