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 was just playing Oracle of Seasons on a GBC emulator on my Vita yesterday. I love the PSP and the PS Vita, severely underrated especially with all the CFW and homebrew options.
I even used Moonlight to grind life skills in MMOs from my Vita.
There are some special steps you have to follow to set up seeding from a VPN, but they have a guide for it and it isn't that complicated. I'm happy to help if you get stuck.
When you join you will be gifted thousands of bonus points by current members, and you can use those points to buy upload credit to pad your ratio. You also earn those credits for seeding based on time, not actual data uploaded.
In addition, there is a ton of freeleach content available, and it's good stuff too.
myanonamouse.net, a private tracker that focuses on ebooks and audiobooks, is a pretty good place to get started. Registrations are closed, but twice a week they offer interviews to join. The interview is not hard, you just need to be able to answer a short quiz about the rules.
Once you're in it's really easy to maintain your ratios and there is a lot of freeleach content.
I've found audiobooks there that I can't find anywhere else.
I'll seed it if you want to go that route
Another vote for Joplin here, but I prefer to host Joplin server for synchronization because it's much faster than NextCloud.
