Firefox sync incorrectly claims my own server URL is invalid.
I use my own server (implemented in PHP, run on Apache) to sync Firefox instances. The URL is https://diederickdevries.net/owncloud/remote.php/mozilla_sync/. Firefox Desktop (version 27.0.1 on Arch Linux) syncs without problem.
However, when I tap "Connect", Firefox on my Android device (version 27.0) asks me to enter a valid server URL, implying what I entered isn't correct. My Apache acces/error logs do not mention anything trying to access that URL at the moment my phone's Firefox states that it is "Verifying".
Is there a log on the phone that I could check? Is this a bug? How should I proceed?
Thanks for any help, Diederick de Vries

I notice you have a self-signed SSL certificate. There is a bug on file indicating that this is a problem: 756763 – Android Sync can't accept self-signed certificates (or roots unknown to Android) for custom Sync servers on Android 2. There are a number of other bugs related to this error message, and I'm not sure which is the most relevant, actually.
You will need to import the self-signed certificate into the Android certificate store.
Hi, Thanks, but I'm unsure how to do that. I've copied the crt file from my apache installation to my phone, and when I tap on it in a file manager, the phone proposes to open it using an installation app for certificates. However, when I tap it, it tells me it cannot read the file. The log says:
[ 03-04 22:40:05.782 4815: 4815 E/CertInstaller ] Failed to read certificate: java.io.FileNotFoundException: /storage/emulated/0/.../server.crt: open failed: EACCES (Permission denied)
It has 0660 permissions, but I cannot chmod it to 0666: I don't have the rights.
How should I install the certificate?
I don't know. Never had the need to add a custom certificate to Android. https://encrypted.google.com/search?hl=en&q=Android%20add%20self%20signed%20certificate
I imported the certificate using Settings -> Securiy -> Install from sdcard, but the phone's log still says:
[ 03-09 10:51:42.342 18284:19573 I/FxSync ] firefox :: EnsureUserExistence :: Error checking for user existence.
[ 03-09 10:51:42.342 18284:19573 W/FxSync ] firefox :: AccountAuthenticator :: Authentication failed. javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
What certificate should I import then?
I don't know the answer the #sync irc channel on irc.mozilla.org is where I would suggest asking your question.
