You can change the values in wp-config.php and get your site back. See:
Changing The Site URL
On the Settings -> General screen in a single site installation of WordPress, there are two fields named “WordPress Address (URL)” and “Site Address (URL)”. They are important settings, since they control where WordPress is located. These settings control the display of the URL in the admin section of your page, as well as the front end, and are used throughout the WordPress code.
The “Site Address (URL)” setting is the address you want people to type in their browser to reach your WordPress blog.
The “WordPress Address (URL)” setting is the address where your WordPress core files reside.
Note: Both settings should include the http:// part and should not have a slash “/” at the end.
Every once in a while, somebody finds a need to manually change (or fix) these settings. Usually this happens when they change one or both and discover that their site no longer works properly. This can leave the user with no easily discoverable way to correct the problem. This article tells you how to change these settings directly.
Additional information is presented here for the case where you are moving WordPress from one site to another, as this will also require changing the site URL. You should not attempt to use this additional information if you’re only attempting to correct a “broken” site.
You can change site url by following 4 method:
BY editing the Edit wp-config.php, Edit functions.php, Relocate method, Changing the URL directly in the database.

So the thing is, I can’t access the admin panel (dashboard) anything, I have a 404 error when I try to log in to the admin. Can it be reset somehow? or maybe I can detach the domain somehow?
