Cant Access ANYTHING- Blank Login Page

I tried to start my WD mycloud after a few months of inactivity. I´ve never used it that much its is basically a storage grave.
When trying to access the login site I get a blank page and a lot of jquery errors within the console when using the inspect mode.
Jquery is probably not the issue here but why doesn´t the page load at all?
How can I access the admin panel and is there any way to debug this or get a log?
Thank you for your help!
