MK3S+ displaying "new firmware available"

Hello,

I've been using my MK3S+ for a little more than one year, made several firmware  updates, no trouble at all. Printer is managed through Octoprint.

Today (I should have taken a photo, my bad), the printer displayed a message saying "there is a new firmware 3.12.1 available, please upgrade". That is quite nice (except I did upgrade to 3.12.1 and then went back to 3.11, but that's another story).

My question is the following : how does the printer know there is a new firmware available ? Since it's not connected to the outside world, no way it can have reached any update server. Could it be Octoprint (which can reach the 'net) ? But then why not display this message also in the web  interface (I checked, nothing there, nothing in the logs)?

Any idea ?

Thanks.

In your start-up .gcode.  Note that I have it commented out.

;;M115 U3.9.2 ; tell printer latest fw version

Thanks !

I did not know there was this control inserted into the startup Gcode. I commented it out, as you did, for the time being at least.
