Hi, if admin has forgot the password and request a new password an email is been sent to the admin but with the IP of the server not private ip so link doens't work.
You know in the end user there are two IP one is the IP of the server and one is the private IP.
In my case i have receved the email with reset link but with IP of the server so didn't work, i have solved manually changed only the IP with my private ip and copied the rest of link.
