Hello, I wanted to use xmrig-amd-v2.14.4 to mine Monero and it all starts well, mining works for a while but then it stops for no obvious reason and the pool is sending new jobs, but nothing is mined. Can someone help? I am using this syntax: -o xmr-eu1.nanopool.org:14444 -u address.$rigName -p x --donate-level=1 --print-time=5 --api-port=3333

and this is how it looks in the log file when nothing is actually mined:
