Impossible to run n8n behind an implicit proxy

[whatthegit]

Describe the problem/error/question

I had to build the Dockerfile and after jumping many hurdles, the image was finally built with proxy support. Or so I thought. When running the image, I encountered the errors below. It seems to me that the product is not properly designed for corporate use, which most companies use proxy servers. Why are companies’ need to use proxy servers ignored, when they are likely to be the main paying customers? Anyway, I went through so many articles here and elsewhere but nothing helps.

What is the error message (if any)?

I managed to get proxy support for Docker, NPM, etc to work, but after trying 3 days just to get the basic interface up, I’m stuck at proxy support for Axios.

Hey @whatthegit,

Welcome to the community

Axios has a known issue if you are using an HTTP proxy with HTTPS endpoints as it can’t handle the CONNECT method correctly. We do have a dev ticket opened to work around this in the future and it should be resolved soon but for now the only option would be to have an https listener on your proxy as well.

Thanks @Jon .

So I just need to have a HTTPS listener, and point HTTPS_PROXY environment variable to it, will do?

From what I researched, this issue had been around for a long time. I just find it such a waste that due to this, a lot of companies just simply cannot proceed further with n8n as it doesn’t work will proxies properly. There is definitely a lot of opportunities lost, and I am certain that once this is resolved, business will become better for sure.

Hey @whatthegit,

You got it and I am sure you are right, Oddly enough though for most of our current enterprise customers this has not been an issue that doesn’t change fixing this but it is interesting to know.
