Consistent BLTouch issues trough Octoprint

What is the problem?
My BLTouch (original Creality Kit) is having repeated problems during the execution of the "G29" code that is in my gcode before any print.

9 out of 10 times the probing fails and the printer resets connection.

When I try to make a bed level mesh trough the Bed level Plugin, it usually works.

When printing the same gcode trough SD Card, probing works 9 out of 10 times...

What did you already try to solve it?

Printing trough SD card, auto test the ABL, switch fans on/off during probing.

Logs (octoprint.log, serial.log or output on terminal tab, ...)

I'm not sure where to get these... :frowning:

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, ...)
I'm using Marlin 1.1.x bugfic, the lates Octoprint version, a good power supply for the Pi 3b+ (this the i has no active nor passive cooling, but I don't get error messages)

That sounds more like a printer problem than an octoprint problem.
I got the newest kit like 2 month ago and used this guide to get it working on marlin 1.1.9 vanilla.
I would suggest you compare the settings from the guide to your settings and look out for differences.
