SSL working on desktop, but not on mobile (Android) devices

If the SSL certificate on your site works fine on desktop but gives an error on mobile devices (specifically Android): this certificate isn’t from a trusted authority, there is probably an issue with your SSL certificate chain.

To check this, run an SSL check here:

If one of the results is This server’s certificate chain is incomplete. Grade capped to B, this might be the issue. Contact your hosting provider to fix your certificate chain.
