Everytime i try to add an external storage, if it asks for the admin password, it will says incorrect password
password is good, can login with it

Additional info

login/logout no changes
firefox / edge no changes

BUT in command line -> no issues, can add the external share without issues

in nextcloud logs, the first request is a wrong password, then immediatly the good password

[huntervcx]

Just reinstalled nextcloud 26.0.13
works out of the box, exactly same setup
didn't even ask for password confirmation

[provokateurin]

@huntervcx please don't use such an old Nextcloud version that hasn't received any security updates in years.
