easiest way to check if there blocking is at work connect to the same network and simply ping your pool, in windows open cmd, ping xxxx (replace xxxx with pool and port )
Topic: 5 Antminers down, can't get them back up ? (Read 1084 times)
Wonder if they are blocking/filtering traffic to the mining pools...
Thanks for the quick replies. Yes, I thought about this too but they should show up on the network and I should be able to log into them via a web browser. I also asked them and they said they aren't blocking anything. Strange..
Assuming your IT department is big, it doesn't mean much if some guy there told you they didn't block anything.
My best guess here is that they blocked your miners MAC addresses.
Sometimes when I restart my network I have to power cycle everything before the miners will start working...I think it has to do with network congestion from low difficulty shares.
I also have a network hub that will block my miners completely if I plug it in...something about multiple dhcp.
Try pointing them to a different pool, but it really sounds as if they blocked your miners.
Ask the network/IT guy if there's any sort of MAC filtering or if he can allow your miners to connect manually.
Send me a PM if you end up having to sell those sexy s7-ln's.

Greetings, My first post !! Thanks all !!
I have 5 total Antminers all running at my office. 2X Antminers S7-LN, 2X Antminers S5 and 1 Antminer S3. All were running perfectly for weeks at my office. Over the past weekend, they all stopped mining. I VPN'd into my office and was able to connect to them all, but they all showed DEAD under mining status so I rebooted them all. None of them came back on the network after the reboot. I couldn't connect to them with a browser and was unable to ping any of there address. I spoke to our IT department and long story short, there was an issue with a Cisco switch so they rebooted the switch and they said everything should be good. I rebooted the S7-LN miners and had a red LED and was unable to connected to it. I tested the Ethernet cable going to it with a laptop and was able to get online, no problems. Both S7-LN have the same issue. I also rebooted the remaining miners and none of them mine. Seems like same issue. I factory defaulted both S7-LNs and still same issue, red LED.
Does anybody know what could be causing this ? Is there a known issue with Cisco switches working with Antminers ? Any help would be greatly appreciated !!!
Thanks,
Mike

okay first determine your miners were not killed off some how and won't work any where at all.
I.e. pick an s7-ln bring it to your house and see if it works.
If it works and all your other miners work in your house.
you can try buying this
https://www.amazon.com/gp/product/B003CFATSS/ref=oh_aui_detailpage_o00_s00?
cisco switch ------------ your office eth wire ------------- >> dsl router above to eight eth out ports plug in a laptop and your miners
you should be in a 192.168.1.1 to 192.168.1.254 sub net work
load advanced ip in the lap top.
scan the 192.168.1.1 to 192.168.1.254 sub net work you should find the miners and the laptop .
note may not work depends on wtf your it guys did.

There are just so many possibilities out there. You mention an Ethernet cable working on laptop but not on miner. You might ask if they are using anything with mac address whitelisting where authorized devices only can't connect.
It sounds like something changed over the weekend on network side. And again assuming it's modern Cisco gear it's hard to say what all it could be. You might bring one of the miners to the networking person/persons and see what they see when connecting as I would guess they have much more information then you have on network logs.

You are going to need to talk to the "IT Department" most likely. No there is not a issue with mining UNLESS your company has blocked something, which we cannot know. There are a ton of things they could do to block your miner's or the trafffic. There are so many scenarios it's hard to saw what they could be blocking.
Are these something your company has authorized to run on the network? If so I would think one of your networking personal would be able to help much more then vague guesses you will get here. We just don't know enough to be of much help with info provided.
