We recently switched a site to all ssl, and since it is a cpanel enabled litespeed, this has enabled http/2 under the current litespeed version 5.0.9. We allow file uploads via a web form with ajax meter to show the progress. This was working fine, but after switching to http/2 we noticed that users were not completing uploads. After investigating, we found that by switching off ssl, and therefore disabling http/2, that the uploads completed much faster. The bigger issue is that with http/2 enabled the ajax progress meter would stop responding before the upload completed. This caused the user to abandon the upload as it appeared that that progress had stopped, even though it was still uploading and upload would eventually complete if they didn't abandon.
Any idea why this might be happening? Is there a way to disable http/2 only for certain pages or actions with litespeed using the cpanel plugin?
