Probably wrong url then. Not sure what url to put in, did you find this URL in an example and then copied it for your instance?
might be as simple as removing the / in the end or the last login bit.
Generally, with logging to a service, a few things you could be checking:
App Password Not Enabled or Valid
(see if the profile lists the app password and it is valid / not revoked)
Basic Auth Blocked by Hosting Provider
(well, that you can’t check yourself, but can ask)
Wrong Base URL
(a url you use as the url to your wordpress, your last screenshot suggests that the one you need to use is without /login, just have to get the creds right)
Incorrect User Role
(does your user have sufficient permissions?)
Security Plugins or .htaccess Blocking REST Access
(if you haven’t configured, it would be, I guess)
