Failed to load CSS during playback "NoSuchKey" - Self Hosted Ubuntu

Issues & Bugs
1

When trying to play a recording, the screen looks like there is no CSS.
Checking Dev Tools console log, I can see errors such as:

Refused to apply style from ‘https://openreplay-test.*.com/sessions-assets/https%213A%212F%212F-mydomain.com%212FModules%212FShared%212FSideMenu%212FSideMenu.css.17’ because its MIME type (‘application/xml’) is not a supported stylesheet MIME type, and strict MIME checking is enabled.

When trying to get this asset directly, the self hosted server replied with such XML:

NoSuchKey
The specified key does not exist.

How can I check why it happened and hopefully fix it?
Note that both the self hosted OpenReplay server and the actual server used in recording are in the same intranet and should be able communicate with each other. While both are not accessible from the internet.

Thank you

This usually happen when OpenReplay is unable to download and cache the css file. The best way to ensure that, is to run a cURL from the OpenReplay instance on that css file and see if you can get it. Or you can also check the logs of the assets service to look for errors:
openreplay -l assets
