Are you using Brotli compress format? I think we don't package this in the final binary.

[wu-sheng]

I have no idea. Both are working on my side.

[wu-sheng]

9.2.0 was using Spring Webcontainer, if I remember correctly. The UI package is much larger. We changed to the armeria lib.
Maybe you are always using the Brotli compress format? You just don't know? Check the HTTP header, I assume Brotli is there, most ppl are using gzip only.

I also tried. 9.3.0 has no problem on my local machine, but it doesn't work on the ubuntu machine

That is what I thought. You could ask for suggestions from the Armeria community. They have experts.
