How to resolve Heimdall seed connection errors?

I'm having trouble with my Heimdall node not being able to connect to any seeds. I've followed the docs and started the Bor service, but I get errors like 'Couldn’t connect to any seeds' and it seems the Heimdall rest server shuts down. What steps can I take to resolve this issue and ensure my node connects properly?

You may need to clear the addrbook.json file. Here's how:

  1. Open the config.toml file: vi /var/lib/heimdall/config/config.toml
  2. Stop the heimdalld service: sudo service heimdalld stop
  3. Clear your addrbook:
    • sudo service heimdalld stop
    • cp /var/lib/heimdall/config/addrbook.json /var/lib/heimdall/config/addrbook.json.bkp
    • rm /var/lib/heimdall/config/addrbook.json
  4. Increase max_num_inbound_peers and max_num_outbound_peers in /var/lib/heimdall/config/config.toml:
    • max_num_inbound_peers = 300
    • max_num_outbound_peers = 100
  5. Restart the heimdalld service: sudo service heimdalld start. It's also suggested to add the necessary entries in persistent peers and try once before following the steps above.
