Beware on 2019 firmware just want to let you know that it may disable your SSH access if you flash it with 2019 firmware so make sure to flash it lower than 2019 firmware.

This is not a "may"; it is widely confirmed. Only use firmware up to 2018, such as December 2018 or earlier.

Or switch to Braiins OS, the open source firmware replacement. you won't regret it.

It was sold like it was new. This one was the only different both visually (different fan on the back) and batch number.
I will flash it. So far it's working as it is supposed to.

@OP, is this a new miner directly bought from Bitmain or was it bought used (and from who)?
If bought used then this is a prime example why it must be said to ALWAYS reset/reflash ANY used miner because the the world is full of assholes looking to steal from anyone they can...

It looks like someone monitor your miner or your PC check this detailed IP location and host name below.

IP Address : 37.252.254.172

Another one is this

IP Address : 217.146.8.70

Location   : Serbia (95% accuracy)

Do you have installed teamviewer in one of your PC while you scanning these IPs?

Try to remove it and scan it again let's see if it will remove this 2 IPs.

I would just block what shouldn't be there.

Thanks! Also would you block everything except pool ip or leave some other address allowed?

I've never heard of RIPE / RIPE Coordination center. My suggestion is to first block those IP's on your firewall. Then factory reset the miners by flashing the NAND with an SD card.

Guys, I've bought some S9j's recently. They are working fine, but I've noticed one thing. One of the machines has too many connections beside the pool ip address. It connects to the following addresses: 217.146.8.70 and 37.252.254.172.
Is that OK? What should I do?
