Wallabag not working with KOreader in Kobo Forma

[Hhvh]

Hi all,
I've registered a Wallabag account with paid hosting in app.wallabag.it.
I've successfully synchronised it with both Edge and Chrome extensions, and with my Android smartphone too.
I've also configurated KOreader for Wallabag in my Kobo Forma, following the same steps: creating a new client in my account and copying the Client ID and Client Secret data in the wallabag.lua file, as well as my User Name (in this case I have tried both with my username and my email, just in case) and password. However, when trying to fetch my saved articles in my Wallabag account, I get a "Unable to login" message.
Any help?
Thank you in advance!

Thank you. However, I had already followed all those steps and hints before asking.... without success

The URL should simply point to the homepage (e.g., https://mobileread.com, if that were Wallabag).

I'm not sure I'm understanding you well. Which url? There's only a "server_url" in the Wallabag account settings which, acording to the instructions, should be void.
If you are talking about the article's url, this is not the problem, since I can get articles stored in Wallabag from my Android device. The problem is connecting KOreader in my Kobo forma to my Wallabag account.

The server URL should be the server URL.

So I understand in case I have subscribed to wallabag.it, the server should be htpps://app.wallabag.it
Am I right?
I've tried it, but still does not work. And Wallabag.it user's service does not reply.

Thank you to all that have helped.
Even when I have got no answer from Wallabag.it, it has suddenly begun to work, so I think they have fixed something, because I haven't changed anything in the configuration.
