Tunnel Troubleshooting

Setting up a secure tunnel involves configuring several different networks to work together. When setting up your tunnel it is common for traffic to initially not reach your destination initially. This is almost always caused by configurations (firewalls, VPCs, IAM rules, etc.) in your internal network.

Tunnel Logging#

The tunnel by default logs only errors. For the purposes of debugging, it is useful to set a more verbose log level. To set logging to a different level, simply set the environment variable TUNNEL_LOGLEVEL on your Zuplo tunnel instance to debug. Other log levels available are info, warn, error, and fatal, but debug is recommended for troubleshooting.

The way you set an environment variable will vary depending on where you deployed the tunnel. See your cloud provider's documentation for more details.
