No traffic recorded for an app on localhost in Chrome with FoxyProxy Standard

Ulf | Last updated: Apr 13, 2019 11:24PM UTC

I set up the DVWA in a Docker container which binds to localhost on port 80. The web app opens just fine in Chrome. I'm using FoxyProxy Standard to configure my proxy settings in Chrome. Every other traffic is being recorded, localhost traffic isn't. I already tried whitelisting localhost explicitly with no success. Please help.

Have you tried editing your hosts file? Alternatively, could you try using another browser?

Meanwhile I tried using Firefox, that worked fine. Seems to be a Chrome issue.

I've suffered an identical issue using OWASP ZAP. Works in Firefox capturing localhost website traffic for Juice shop on port 3000 and DVWA on port 80 but not in chrome where it captures all non localhost website traffic but not localhost traffic itself.

I found the following Chrome documentation that might be useful: - https://chromium.googlesource.com/chromium/src/+/HEAD/net/docs/proxy.md#:~:text=manually%20configured%20proxies-,Overriding%20the%20implicit%20bypass%20rules,of%20subtracting%20the%20implicit%20rules.
