From the log I can see that you have 0 peers, and that could be the issue, since without peers you do receive transactions, so the real issue to see here is peering, check if the Besu p2p port (by default 30303) is reachable from public internet, and in case adjust your firewall.

The port was open and a restart started finding one or two peers.
