Two possibilities but you narrowed it down to gas. The tank has an OPD.
(overfill protection device) that tends to cause problem when the gas is
turned on too fast on a full tank. It blocks the flow. Shut everything
off, wait a few seconds, then slowly open the gas valve again. Some grills
warn of this in the manual. Once the liquid level in the tank goes down a
bit this won't happen again as the float level will be down a bit. .
Others have reported having to bang on the tank to get the OPD to release
but that is rare.

If you don't have one already, get a spare tank so you don't run out in the
middle of cooking dinner.

If the air is very humid, the sparkers on some grills just don't work as
well and the lack of good arc fails to ignite the gas.
