I can't sign in

Check these first

• Typing: passwords are case-sensitive. Check the server address has no extra spaces.
• Changed password: if you changed it in another app, use the new one everywhere.
• Old QR code: the code in your welcome email may stop working after a password change. Show a fresh one from Communicator Next. See Sign in to Communicator.
• Connection: open a website to confirm you're online. Try switching between Wi-Fi and mobile data.
• Date and time: make sure your device's clock is set automatically. A wrong clock can cause certificate errors.

Certificate or security error

The app checks the server's security certificate before connecting. If it warns you, don't continue. Tell your administrator: it can mean the server address is wrong or the network is intercepting traffic.

Account locked

Too many wrong attempts can lock your account for a while. Wait, or ask your administrator or service provider to unlock it and reset your password.
