Troubleshooting Connection Problems

If your node startup fails with messages like "Could not connect" or "All bootstraps are faulty" please go threw the following checklist:

For all types of networks, please check:

• TCP AND UDP must be allowed to pass your firewall ports used by the node (usually 9011, 9085 or similar)
• DNS is provided and allowed to be used by the LAS2peer instance

Local only networks

This means local restricted networks including networks behind NATs and/or firewalls, but with no connection to the internet. Usually found at home or inside institute networks.

• verify that firewall_test_policy = never and nat_search_policy = never are specified inside the pastry node configuration file.

Internet Wide Networks

This means at least more than 5% of the nodes inside the network are reachable over the internet.

Connect From Home

To configure a node running inside your home network (NAT and firewall) please see our detailed article, here.

Connect From Cloud Solution

This means you have a node running inside a cloud solution with NAT, but no port forwarding requirement.

• verify that external_address = 123.45.67.89:1234 is specified inside the pastry node configuration file.
