Strange Issue with Z9-mini

[Xazax310]

Hey all,

I currently run a few Z-9 Mini's and sometime during the early morning 5AM or so they all Ramped up in fan speed (so very noise woke me up) I checked and they all stopped hashing. I shut them down, but when i restarted them they would just endlessly reboot(Fans' ramping up/down continually). I remoted in via IP and saw they were not getting any network connection. Checked all my network settings, My personal computer/phone could reach out fine, but any of the Ant-miners could not using the PING built into them. I unplugged my Modem, Router, and switch. Plugged them back in and still couldnt get them to hash.

Having messed with them for an hour I had to leave to work. I shut them all down. I come home now, turn them all back on and POOF they all work and are running normal again. What the hell happened?

Heat?
They are in an Airconditioned Room that's always at 70F, board temps I never have seen more than 65C(Temp Chip) on a hashing board.

Overclock?
I Do have them overclocked but they've been running fine for over 2-3 weeks before this happened without any crashes or serve loss of hashrate.

Network?
I unplugged my Modem, Router, and switch. Plugged them back in and still couldn't get them to hash.

The only error I received was on the mainpage saying

"antminer Hardware Version Socket connect failed: Connection refused"

Mind you this wasn't a single Antminer Z9-mini this was all of them that happened and all at the same time, all had the same error. I'm glad its working now, but I'm stumped as to why it failed.

"antminer Hardware Version Socket connect failed: Connection refused"

This isnt an error per se...this just means the miner executable wasnt running, therefore the console could not query its status. I think to figure out what happened you would have had to dive in a little deeper while the problem was present. SSH in, run network diagnostics from there and not the web page, etc.

Do you have a backup pool set? Maybe your pool went down for a bit?

Sometimes a higher quality ETH cable fixes this.
