NetworkError when attempting to fetch resource (only with Firefox ?)

Kirby 4 Question❓
1

Hello,

My site is working.
I can access the panel, import files and save changes… but sometimes I get this error message : “NetworkError when attempting to fetch resource”
this error appears even if I do nothing on the page

Firefox console :

k4_error_fetch
k4_error_fetch800×473 102 KB

Same error with a fresh starterkit on this domain.

Php 8.2.10
Apache
Hosting : OVH (Shared hosting)
DNS : mydomain.com with A and www.mydomain.com with a CNAME
Kirby 4.1.2
htacess : redirect http to https
Server error log : nothing for my ip adress

Does anyone have any ideas ??

Everything is fine with chrome
This seems to be a problem with firefox… ?
