Unable to play/stream videos from HBO Max

[KNTRO]

Hello,

I'm facing troubles when I try to play/stream videos from hbomax.com. The website shows an error message and won't load any video. I have tested it under Ghostery Private Browser's Safe Mode as well — same results.

Then I tried it on Mozilla Firefox 102 ESR and Microsoft Edge 112. It worked on both web browsers, so I think it's not a Gecko nor an add-on related issue.

Any tip?
