If you’re open to docker options, I’ve used and recommend ArchiveBox. It supports using a login to rip sites, and you can set it to rip once or on a schedule, etc.

I think they have a desktop app version in the works if you were looking for a more of a one-time approach.

I’d add that it might be worth checking out the JavaScript console as well (F12 > console in most browsers), in case the problem is with the login page

Seconded, and the interview process is not bad, just a few questions about the rules.

Second for MAM, they’re great and well worth the minor trouble to join.

Why don’t you recommend Cloudflare?

I’ll seed it if you want to go that route
