VFS connection does not exist

Question

I'm following the AWS tutorial Build a Modern Web Application - [Python].

I'm at Module 2B: Deploy A Service With AWS Fargate @step B:Test The Services Locally

I run my docker image with success with:

docker run -p 8080:8080 xxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/mythicalmysfits/service:latest

When I preview the website on AWS cloud9 I get the following error.

Oops, VFS connection does not exist

I've tried the following:

• created new docker image on different region
• checked the flask app routing (all good)
• double checked my account id
• checked AWS documentation

All of this and I can't figure out what is going on with the error. Am I missing something?

Answer 1

1. Do not run Cloud 9 in a browser in Incognito mode.
2. Remove add blockers
3. Check the docker run output for errors

Answer 2

I found the solution and that is to open the console in chrome and do the docker run there.

Here's what it looked like for me

Answer 3

I found the solution! - Ad Blockers! As soon I disable them, It worked

Answer 4

My solution is to use the same (normal) browser, not private mode/incognito window.
