Getting a message when trying to login to upload or retrieve from cloud or mobile?  Here are things to check.

Validate failed or a Null error when logging in usually means either (a) one is not currently signed up for Cloud, (b) the account subscription has expired and was never renewed, or (c) either the login email or password being used is incorrect for the account.

Are you a new user?  Have you signed up to enable your free Cloud3D Services account?  If you have never used Cloud3D previously, use the sign up link on the website Mobile apps page under Products to enable an account- see the step by step setup in section C on the mobile apps page.

If you were using Cloud3D previously without issue, are you sure your subscription is current and hasn't expired recently without your renewing?

If this is a new device you are logging into, make sure no extra spaces got added before or after your user name or password. Also note the user name / email is not case sensitive, but the password would be.  Try backspacing out both items out completely and entering them completely fresh and carefully.

If you are the only inspector, then you may use your master activation ID and password or a sub account login you create for yourself (which may be easier on a mobile device, or if you want to use an alternate email or login there).  If you are not the only inspector, then must not use the master login or activation password to avoid data loss, but should instead set up and use a sub account login that you create in the desktop software for yourself and other inspectors to access your assigned mobile app inspections on your device: https://3dinspection.com/en/tips-and-tricks/managing-multiple-inspectors-with-phone3d.html
You may also do this if you are the only inspector as well if you have forgotten your password or simply want a simpler login or to use one that uses a different or newer email address you can set that up for yourself as a subaccount to use on your mobile device.

If you are an inspector or sub contractor working for the registered user, the software user should have assigned you with your own sub account login to use on your mobile device.  Verify with them that they have done so or obtain that login (usually your own email) to use to access assigned inspections. If you or they need direction, we suggest sending a ticket to support for assistance.
