Hello,
My miner has been rebooting every 30 minutes, and I don't know the reason; this didn't happen before. I live in Ukraine and am connected to solo.ckpool.org because it offers higher hash rates, which I believe increases the chance of finding a Bitcoin block. I also tried connecting to eusolo.ckpool.org earlier, but I couldn't. My ping is around 140. I can't figure out why it keeps rebooting; perhaps someone knows. Thank you

Hello, From France, latency observed this morning, for solo.ckpool.org 141 ms and for eusolo.ckpool.org 11 ms where I am connected.
I don't think it's linked to the pool, but rather to your hardware. To rule out any problem linked to the ck pool, test several hours of connection on another pool
