Netflix erreur

Hi everyone,
I'm reaching out because I'm completely stuck with Netflix on my Formuler Z12 Ultra. Every time I launch it, I get the exact same message: "There is a problem connecting to Netflix. Please try again later (-12)."
My internet connection works perfectly for all my other apps; it's strictly Netflix that is blocked.
To save time, here is everything I've already tried (with no success):
Cleared the Netflix app cache and data.
Completely uninstalled and reinstalled the app.
Verified that the system date and time are set to "Automatic" (network-provided).
Performed a full power cycle of the box (unplugged from the wall for several minutes).
Restarted my internet router.
Changed IP settings to static and updated the DNS to Google's (8.8.8.8 and 8.8.4.4).
Despite all of this, the -12 error persists. Has anyone dealt with this issue on this specific model or have any alternative tricks I haven't tried yet?
Thanks in advance for the help!
