Mitra 7206 will not start up

No, on the main electrical outlet of course (I would never advise to modify a GHL product, even less on a waterproof connection!)
The purpose of a timed relay is to wait xx seconds before powering up. So you have to delay the restart.
The problem occurs when the power supply is de-energized and re-energized too quickly, without having enough time between the two.

Thanks for clarifying that. I didn't understand how delaying the mains would help. That would explain why sometimes they power up successfully. Usually I only wait about 5-10 seconds before plugging them back in. I'll try leaving them unplugged longer next time.

It is necessary that the capacitors discharge completely, and the brightness of the lamp at the time of the power cut also has an impact
