Troubleshooting

Fix common Proxyman Automatic Setup and Manual Setup problems: missing traffic from NodeJS, Python or Ruby, SSL errors, and localhost requests.

1. Automatic Setup does not capture any HTTP Traffic from my new networking library​

Proxyman supports the following libraries:

  • NodeJS: Axios, got, superagent, fetch, and node-fetch
  • Python: http, https, aiohttp, requests
  • Ruby: http, net/http, net/https, faraday, and httparty

-> If you're using a new library and Proxyman Automatic Setup doesn't capture your HTTP/HTTPS traffic, please create a new ticket on GitHub to request support for your library.

info

If your library running on your Mac ignores proxy settings, try Network Extension. It captures supported HTTP/HTTPS traffic without relying on Automatic Setup's proxy configuration. Certificate trust is still required for HTTPS.

Network Extension is BETA and requires Proxyman PRO on macOS 26 or later.

2. I get SSL Errors from my NodeJS, Ruby, Python script​

-> Make sure you've installed and trusted the certificate on macOS. Open the Certificate menu -> Install Certificate on this Mac….

-> If the error still happens, there may be a bug in the Automatic Setup feature. Please create a new ticket on GitHub and let us know.

3. Proxyman could not record any traffic from my local server, e.g http://localhost:3000​

By default, traffic from http://localhost:3000 doesn't go through the system proxy. Therefore, Proxyman can't capture it.

Follow I could not see any requests from my localhost server to fix it.
