What could potentially be the cause of that?Exactly. Could still be in some kind of unstable LEO for all we know. They were at 195 km altitude and 7.02 Km/s velocity at TLM cutoff. If it was a propulsion problem, they could be in a (really) low orbit.

If ESC-A was able to release SES-14, then the Sylda, then Al Yah-3 it must have worked to some degree.If the engine failed right when the telemetry was lost the sats probably would be lost by now. (Edit: If someone knows better, please correct me!)
Strange that the objects (ECA, sats and adaptor) have not yet been tracked. Usually happens within two hours of launch.

Success!"Stéphane Israël @arianespaceceo41m41 minutes agoVA241 update: lack of telemetry after ignition of the upper stage lasted the rest of powered flight. Both satellites confirmed separated, acquired, on orbit. SES-14 and Al Yah 3 communicating with their respective control centers. Both missions continuing"https://twitter.com/arianespaceceo/status/956698000004395008
Too early to say that. It's also just a repost of the Arianespace press-release: http://www.arianespace.com/press-release/va241/
So all good then?
Yahsat's press release just a copy-paste from ArianeSpace.http://www.journeyofpride.com/ariane-5-launch-va241-for-ses-14-and-al-yah-3-update/OrbATK (builder of SES-14) then retweeted it.
OrbATK (builder of SES-14) then retweeted it.
Quote from: Flying Beaver on 01/26/2018 01:50 amOrbATK (builder of SES-14) then retweeted it.Correction, OATK build Al Yah 3. Airbus built SES-14.I saw further up in the thread that this was the first SSTO mission for Ariane. Does anyone know why this mission was SSTO? I didn't hear a technical reason for why on the live stream. I was under the impression a super synchronous orbit could help reduce the Delta-V if an inclination change was required (like a SpaceX mission from Florida), but that clearly isn't the reason this time.
Yahsat update, in arabic I think.http://www.journeyofpride.com/ar/%D8%AA%D8%AD%D8%AF%D9%8A%D8%AB-%D8%AE%D8%A8%D8%B1%D9%8A-%D9%84%D8%A5%D8%B7%D9%84%D8%A7%D9%82-%D8%A7%D9%84%D8%B5%D8%A7%D8%B1%D9%88%D8%AE-%D8%A3%D8%B1%D9%8A%D8%A7%D9%86-5-%D8%A7%D9%84%D8%AD%D8%A7%D9%85/"The carrier rocket was launched satellite Eliah 3 on 25 January 2018 at 7:20 pm. After a few seconds of launching the rocket, the upper part of the engine did not receive the second tracking station, located in Natal-Brazil, telemetry data.Interruption of the missile tracking data for the duration of the flight. Later, he was sure separation of satellites of the rocket to initiate the walk in space orbit control technical group. Right now is controlled by satellites SAS-14 kept him 3 through their respective command centers. We would like to confirm the progress of satellite access campaign happenings to tropical locations."
That sounds like the Arianespace press-release. It's just been mangled by having first been translated to Arabic and then run through a machine translator back to English.
