Describe the Bug

Observed behavior

I start with an 'hello worker' initialization project. When I run npx wrangler dev and visit http://localhost:8787/, I get 'Hello world', which is expected. However, the terminal shows the error 'Failed to register worker in local service registry TypeError: fetch failed'. It might be a normal error since I'm in Mainland China and cannot access websites like YouTube and Google without a VPN.

When I execute npx wrangler dev --remote and navigate to http://localhost:8787/, the browser consistently remains in a pending state. Additionally, I encounter the error '✘ [ERROR] Error while creating remote dev session: TypeError: fetch failed' in the terminal.

When I activate ClashX VPN and execute HTTP_PROXY=http://localhost:7890 npx wrangler dev --remote, accessing http://localhost:8787/ still results in a perpetual pending state. After some time, an error message appears in the terminal: '✘ [ERROR] Error in ProxyController: Error inside ProxyWorker { name: 'Error', message: 'internal error', stack: 'Error: internal error' }'. Despite this, I am confident that my VPN allows me to normally access websites like YouTube and Google.

Expected behavior

When I run HTTP_PROXY=http://localhost:7890 npx wrangler dev --remote, works api can work normally.

Steps to reproduce

A 'hello worker' initialization project.

Perhaps the VPN has no impact.
I'm in Japan and don't use VPN, but I get the same error if I have the --remote option.
I'm specifying the remote option because I want to use a non-local R2.
Hopefully this will be resolved soon.

Mac 13.3.1
wrangler 3.31.0

I think we've run into problems with this before, and unfortunately if you're unable to access the Cloudflare API Wrangler won't be able to work. Can you access https://api.cloudflare.com? If not, you'll have to use wrangler dev (without the --remote flag).

wrangler dev --remote doesn't currently support the HTTP_PROXY environment, and so that won't have any effect. I'll leave this issue open to track investigating support for HTTP_PROXY in wrangler dev --remote.

@y-hikaru-walabo it sounds like you're running into a different problem—could you open a new issue with details for us to investigate?
