Hello.

I just sleep for how many years after the burst price increase and now came back just to ask about the miner.

Have you tried to test the s9 first(the not recognize one) to scan while the working one is disconnected?
I feel that one or both s9 is set to static IP that is why one of the miners doesn't recognize. So you must set the miner's network to DHCP to set the IP automatically to dynamic IP.

If you don't know how to do this follow this step.

- first don't connect the one working s9 first and connect the not working s9
- after that scan the IP if you find the IP it means that your both miner have the same IP that is why you can't detect another miner.
- now login to the IP and go to the network then settings you will find the Protocol and change it from static to DHCP apply then restart

Then do the same in your other s9 just to make sure they have both Unique or dynamic IP.

chances are that miner has a static ip that is on a different subnet / gateway .
the only work around would be to reset the miner, this will take it to default setting including dhcp, then it should work fine.
