1. Firstly, double-check your email address spelling (users are identified in the Customer Portal by their unique company email address).
2. Then try retyping your password (especially if the password gets pre-populated in the browser).
3. If this does not help, try retyping your password into a blank document where it is readable to double-check the correct spelling.
If none of it works, try resetting your password and signing in again with the new password (you can refer to the "I forgot my password and want to recover it" article). If this also does not work, please contact CloverDX Support.
