From these 2 errors. I believe the problem is because the browser is unable to find the assets from the server.
This might be due to my setup:
- For my main application, it’s hosted by AWS EC2. All the static / assets files are stored inside AWS S3 folder, and fetched by my app via AWS cloudfront
- For discourse, I installed it in a different EC2 instance using docker image.
- Using AWS Route 53, I added an
Afile that redirects
forum.MYDOMAINNAME.comto the discourse EC2 instance’s IP address
I embed the HTML & JS script inside my main app. When the code calls for the assets, since my main app (in a different EC2 instance) doesn’t contains the discourse’s asset files, error occurred.
If my assumption is correct. How should I fixed this? How can I store discourse’s assets inside S3, served by Cloudfront?
If my assumption is wrong. What do these errors mean and how can I fix them?
