Problem with IOS and yunohost certificates with video upload/play

[jfavart]

When I use Yunohost with Piwigo and a self-signed certificate I always encounter a problem on IOS devices from the IOS application: The access certificate to this server is not valid. You may be connecting to a server that claims to be """, which could compromise your confidential data".

It only happens when playing or uploading videos ... The rest works very well with photos!

Everything works fine outside IOS.

As a last resort, is it possible to disable https on PIWIGO yunohost ?

Thank you !

(I have de last version of IOS/mobile/IPad and update on Yunohost Piwigo).
