Post up your command line / bat or .sh file launching the miner.
Probably something is not properly configed.
You can replace your wallet address with (wallet) for privacy
And what is your dns setting. I use 8.8.8.8 its google.
the miner is run with these options:
--algo ethash --server eu1.ethermine.org --port 4444 --ssl 0 --user 0xwallet.worker --api 3333
DNS: is 1.1.1.1
ping: 1.26ms
query time: 46ms
P.S. in the last 24 hours there were 2 errors where the pool closed connection with this error message:
[2021-09-21 05:44:25] Pool eu1.ethermine.org connection was closed by the pool.
[2021-09-21 05:44:25] Pool eu1.ethermine.org connecting to address 172.65.207.106.

and there were 40 error like i've mentioned about with this message:
02:14:32 Connection Error: Connection closed

as you can see with the "connection closed by the pool" it doesn't write "Stopped Mining on GPU" into the log.
but with the other and most frequent "connection closed" it does write "Stopped Mining on GPU".
