as I wrote earlier, they are disconnected arbitrarily for 3-4 hours and then restored themselves, maybe it is better to remove the ports of dir? bandwidth should be enough running on four cores with 4 GB of memory speed 800/800 Mbps

Hi Станислав

You have two relays running at the same IP. Your IP and relays seem
visible to the network:

 hi, I still don’t understand why the relays constantly go offline for no
 apparent reason


May-be there are indications:

 what it can mean? also my 2 relays go offline for a few hours once a day, then

Port 80 is your DIR port.

If you suffer under potential overload or not enough resources (by what
ever reason) you can reduce.

Run only one relay with OR port only and strict DOS settings. Then wait
a week if everything works. Wait an other week. If still everything is
running well add the DIR port again and wait and wait. Add the second
relay in the same way and finally relax DOS settings.

When ever the relay(s) become unstable go one step back.

This is a recommendation but there might better ways to go.

Good luck!
