"Connection error" or "No internet connection"

Your phone cannot reach the d6 servers. Check that you have Wi-Fi or mobile data enabled and that your signal is strong. Try again in a few minutes.

"Invalid OTP" or "OTP expired"

The one-time PIN you entered is incorrect or has expired. Request a new OTP and enter it promptly. Remember, only the most recent OTP works.

"Detail already in use"

Your phone number or email is linked to another d6 profile. See our article on fixing duplicate profiles to resolve this issue.

"Session expired" or "Please log in again"

Your login session has timed out for security reasons. Simply log in again with your phone number or email and verify with the OTP.

"Something went wrong"

This is a general error that can have many causes. Try closing and reopening the app, or clearing the app cache. If it persists, contact d6 support.
