Can't load .m4a files on iOS browser.

Hi, my exported html5 game can't be loaded using iOS browser (chrome, safari.etc), stuck in loading progress. but if all .m4a files removed, the game can be loaded perfectly.

I think the problem is not my server, i upload it to another server/site, but still get same problem.

My previous game can be played on iOS perfectly (same server/domain) even including .m4a files.

Is someone here know how to solve this problem?

Thank you

iOS 11, C2 r259 and C2 r262

First, be sure to check for errors in your browser, this will provide you with informations as to what is exactly happening/preventing your files from being downloaded.

This could be the MIME types configuration of your server which is not appropriate for those files.

Thank you Kyatric , i will try it
