@bache_plus can you try telnet, if one of 3333 or 443 is reachable for you? This is what you should see if target port is reachable
For port 3333:
telnet solo.ckpool.org 3333
Trying 2620:1e6:100:1605::2...
Trying 51.81.56.15...
Connected to solo.ckpool.org.
Escape character is '^]'.
For 443:
telnet solo.ckpool.org 443
Trying 2620:1e6:100:1605::2...
Trying 51.81.56.15...
Connected to solo.ckpool.org.
Escape character is '^]'.
If there is any issue with network route, you will see "Connection refused" and "Unable to connect to remote host".
Iy you are on windows, you may need to enable telnet command (
https://www.rootusers.com/how-to-enable-the-telnet-client-in-windows-10/ ). Also on windows there is no console output in case of successful connection, you are waiting for console to clear out, if telnet connects successfully.
mikeywith checked it.
Apparently, Talent connects.
