Hello, not sure why my grin-server cannot connect to any peers. It was working fine a few days ago; now nothing. Tried updating to v1.0.1 and bminer v15 but no change. When I run the grin command, the server program loads, but does nothing. I deleted the chain_data folder because someone suggested that to restart the sync, but that didn’t work either. I’m on ubuntu server 18.04. i don’t remember having to forward any ports for the grin program like i had to for grin wallet -e listen. Should i port forward the 3414 in the server P2p configuration in grin-server.toml?

Thanks. Seems to be working now. I had to download the chain_data folder from another computer that was working and replace the chain_data folder on the computer that wasn’t working. Now it seems to be staying in sync. Maybe once a node gets too far behind it can’t catch up?
