Ubuntu 21.04 can't sync #63

Open archerallstars opened 3 years ago

archerallstars commented 3 years ago

OS: Ubuntu 21.04 arm64, Raspberry Pi4 B 8GB

I can't sync with the node. I believe it could be related to firewall settings. What's the port to be allowed in the firewall?

Please help!

Full node port is 9444 - try forwarding that.

Thanks, but it's not my issue. 9444 and 9449 are already allow .. No sync, and always the same messages in debug.log :

full_node spare.full_node.full_node: INFO     Received 11 peers from DNS seeder.
full_node full_node_server        : INFO     Cannot connect to host introducer.sparecoin.org:9444 ssl:
