Thanks for your advice ...
I've tried two pools, litecoinpool and nicehash ...
It seems that with nicehash it holds the connection better, error 127.0.0.1:4028 does not appear, but I am not able to undermine.
At no time does the green light appear, it stays blinking in orange / yellow.
On the dashboard it appears active for a few seconds and is deactivated ... so constantly. Until the miner goes out of line
I have reviewed the credentials and passwords in the pool a thousand times and they are fine, I don't know where to go.
Yea, your putting in the wrong pool info/credentials, as you can see on the top it says "All pools are dead". To rule out any internet issues try deleting all pools from the pool config so it only mines on donation pool, if that also does not work then the issue is with your router/settings.
thanks jstefanop
I have left only the donation in the pool, connect but immediately the miner goes out of line and the connect econnrefused message 127.0.0.1:4428 appears again
I don't know what problem the router can have, I have access to the internet with a fiber connection, and I have no problem connecting to any device ...
What can be?
