I recently purchased an Antminer S19j Pro 104TH/s from Bitmain.
I scanned my router to get the IP because IP scanner wasn't able to detect anything with the physical IP button on the miner.
Miner is connected via ethernet and in the list it says device: unknown, static.
When I try to reach the miner with its IP it doesn't connect, says 'host unreachable', tried ping but same result.
Please help me out here.
First of all, let's just say that the IP report button is pretty useless as far as what you are trying to do is concerned, in fact, it could create issues for you, so stop pressing it, if you bought the miner brand new then it comes with DHCP enabled, meaning that the miner will negotiate with your router and will be given a certain IP within the DHCP table range set on your router.
A good tool to use would be "angry ip scanner" to scan for all devices on the network, if that still doesn't solve your issue, it probably means the miner is configured on static settings which is almost impossible if you bought it directly from Bitmian, but either way, you can just reset the miner and will go back to DHCP.
Also, it's funny to say but please, make sure your network cable is good and that your router has DHCP enabled.
