Operation now in progress

[viktor02]

Hello again. What can the operation now in progress error mean? The fact is that the miner works on my main pc, but not on my server. Debian 10

Its maybe problem with ufw firewall, but disabling it gives nothing. Also, server.duinocoin.com does not respond to pings from any of my systems

[viktor02]

With another system with debian 10 and actived ufw firewall - everything works.

I also updated to 2.2 and the error remained.

Okay, now I am getting an operation now in progress error on the second server and my main machine is also getting server connection errors. I will think that this is a problem on the server.
