Hi everone
An HTTP request component has the ability to set a proxy.
However, an MQTT component does not have proxy settings. What is the solution when the MQTT needs to connect to a public MQTT broker through a proxy?
Thank you for your help.

You can set environment variables http\_proxy / https\_proxy, no\_proxy etc.
See details here: [Perform Proxy logic more like cURL by Steve-Mcl · Pull Request #4616 · node-red/node-red · GitHub](https://github.com/node-red/node-red/pull/4616)
NOTE: this was merged in node-red V4. Prior to v4, I don't think the proxy handling handled MQTT connections correctly.
