I had that same problem when i was using a Satellite internet connection (Hughes Net). I was able to finally get DSL out here in the mountains, resolving the latency problem.
You may have to switch to a cellular modem if you are using satellite.
Your connection shows connection to 127.0.0.1 That would be a network connection to a subnet, not an Internet connection.
Are you on a VPN or internal (work) network?
I use cellular modem (ADSL) bridge modem "localhost is :127.0.0.1"
Internet Speed Test :1,20 Mo/s

"127.0.0.1" or "localhost"always work well for all crypto I mine solo
