Using proxies the browser steps arent loading (ERR_TUNNEL_CONNECTION_FAILED)

[opicron]

Describe the bug Fetch method: Playwright Chromium/Javascript via 'ws://playwright-chrome:3000/?stealth=1&--disable-web-security=true'

When using Brightdata proxies the browser steps are not loading. The browserless/chromium docker exits with: Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED.

When using the proxied watch without browser steps it works fine.

So, my workaround is now:

• Set up watch without proxy
• Select browser steps without proxy
• Turn on the proxy

I can live with that but I thought I should make a note here.

Version 0.40.1.1

To Reproduce Add watch Use Playwright fetch method Select Brightdata proxy Try to use browser steps

Expected behavior I expect the browser steps to load eventually.

How did you configure the proxy? via proxy.json or?

[dgtlmoon]

@opicron when this happens, can you see something in the output logs like Browser Steps: UUID {} Using proxy {}" ? can you paste it? is that value in what it says what you configured?

The proxies are added through proxies.json in the main datastore folder.

When this happens I have to reset the docker because it because very unresponsive.

[opicron]

I changed from proxies.json to the configuration frontend. The same result, fetching works, but browser steps do not work.

[pedrogius]

I'm having the same issue on version 0.41. Browser steps always throws a 400 error. Also non proxied requests all fail, but the visual filter selector still works.
