Hello everyone.
A very old audio player stopped working on the site, was replaced with a new one, tested it on a test server (without connecting to Cloudflare), everything worked perfectly. However, after the transfer to the main server (connected to Cloudflare), problems began: the ability to rewind audio disappeared in Google Chrome and other browsers. At the same time, everything works in Firefox.
For a long time we tried to understand what was going on, contacted the hosting technical support, they said that there were no errors on the server side, but advised us to contact Cloudflare support, allegedly because of Cloudflare such problems occur.
Please tell me what we are doing wrong and how to fix this problem.
