Zcash v2.1.1-1 not connecting to peers


I’ve installed Zcash v2.1.1-1 following these instructions. It started to sync, but after downloading about 4000 blocks it now shows connections | 0, and no new blocks are being downloaded.

The machine is running Ubuntu 19.04, and has 8 GB of RAM.

Log files aren’t showing any errors.

Any ideas how I can fix this?

Can you please post the logs from debug.log right before the node stops downloading blocks?
