colaServer address, username and password
This method normally has three separate fields plus an optional display name. The display name can be a label you choose; the server and credentials must match the access instructions. Preserve capital letters and avoid leading or trailing spaces.
A complete M3U playlist URL
The playlist method uses the whole URL supplied for the account. It may contain credentials in its query string. Treat it like a password. Do not shorten it, share it publicly or replace it with the website homepage.
Portal address and MAC registration
Compatible portal devices use an address plus a device identifier registered for access. A normal player password cannot be substituted for this process. Confirm the device model and registered MAC with support.
When a login is rejected
Check that access is active, the method matches and the address is exact. Avoid a rapid series of guesses. Send the error message and your reference to support without sending passwords through screenshots or public chat.
