no server were found after cgminer raspberry pi os

[abbbee]

Hi all, I'm totally newbie at linux and miner. The GekkoScience compacf stickminer used cgminer on raspbian os. It was fine last few weeks until yesterday I forgot close terninal with Q key instead tick X close straight. Today i fired up Pi and Gekko, only shown below message:

Is this because terminal didn't close correct or something wrong?

Thank you for help!

Are you sure that your Raspi has an internet connection? try to reattach the cable if it is connected through the ethernet cable.

Also, try to replace the pool server or other servers I suggest try this pool below

- https://solo.ckpool.org/


I still do not work bring your issue on their official thread here https://bitcointalk.org/index.php?topic=5053833.0
Then ask for help.

Thanks BitMaxz. The pool i guess it's bound with gekko usb minestick. I found similar thread at 2015, https://forums.raspberrypi.com/viewtopic.php?t=103046&sid=bb1d28d6f7d695a9e9b50de660437d4f#p778336 but no solution, or maybe no one know the answer. And your advised ckpool didn't work either.

Command I used for activate cgminer with GekkoScience Compacf is
sudo ./cgminer -o stratum+tcp://us-east.stratum.slushpool.com:3333 -u [username] -p x --gekko-compacf-freq 400 --suggest-diff 128

Yeah, I used new SD following cgminer installation to raspbian os same result popped. I think the SSH didn't connect or something else. I'll do more searching.

Thanks for helps!

The sticks are not bound to any particular pool. There is another issue at fault.

Apologized delay responded. Kinda busy my current job.

The problem had solved. It's blocked by airprotection on Asus RT-AC88U router. Similar thread like this posted at 2017 https://bitcointalk.org/index.php?topic=1814988.0 But I figured more . I put the pool URL to whitelist, keep airprotection working.

It's all good, everything fine. Thanks for support and help.

Cheers

Apologized delayed responded. As previous posted at March 25, I turn-off router's airprotection (if you have this option on router webUI) then should be solve the problem.

Not all routers have the same settings as air protection I don't have that thing in my router most likely some pools are banned from ISP or blocked from the router firewall disabling it or adding DNS to your pi can bypass this issue and sometimes you need to disable all protection under anti-DDOS attack(SyN/DoS/DDoS) to make your miner work properly or use other pool it should fix this issue.
