1. Linkus server or client version is too low

Make sure to use the latest version on both server and client side.


2. Linkus user is not enabled


Go to Linkus menu, enable the user you need.



3. Incorrect user password

Linkus requires the user password to log in instead of the registration password.


The Linkus login password is the User Password rather than the Extension Registration password.
The default password is random. So you might not know what it is.
You can define a custom one on the PBX web interface for the first time Linkus login. 

Then change it to another password after the first login on the Linkus app.

Or you can send Linkus email with login QR code:

And scan the QR code to login on Linkus App:
