Long URLs are easier to enter with a supported phone remote or keyboard than with repeated directional presses. Preserve the supplied scheme, host, port and path exactly, and inspect the result before saving. An extra space or an automatically changed character can make a valid address fail. A complete playlist URL can carry account credentials, so treat it like a password. Also confirm which field expects a complete URL and which expects only a server address before copying text between them.
Use a private input method
A household phone remote or trusted keyboard can reduce typing errors. Avoid entering account-bearing URLs through a public keyboard-sharing website, because playlist links may contain usernames and passwords. Keep the source message and input device within your control. If you use clipboard entry, copy only the URL rather than surrounding quotation marks, a label or a sentence. Select the actual text field on the television first and review where the pasted text appears; an input method cannot tell whether a server field expects the whole playlist address.
Watch text transformations
Autocorrect, capitalisation and smart punctuation can alter copied text. URLs may contain characters such as a colon, slash, question mark and ampersand that should not be replaced with similar-looking symbols. Preserve upper and lower case in paths and account values, and distinguish an ordinary slash from a backslash. Keep the protocol and explicit port if supplied. Do not remove query parameters because they look untidy: they can identify the authorised account or requested format. If a long field scrolls, inspect its beginning and end separately before confirming it.
Verify before repeating
If the player rejects an address, compare the saved entry character by character with the original message. Repeatedly pasting the same incorrect string does not establish whether the server is unavailable. Separate an input rejection from a source-loading or playback error. If the app accepts the field but returns an authentication message, verify the issued configuration format and current account state with the provider privately. Do not publish the full URL in a screenshot; show the error while redacting credentials and any account-bearing query values from support images.

An example to work through
A trailing space copied from a chat message can turn an otherwise correct server address into a different input that the player cannot use. Remove the accidental space, retain all intentional URL characters and save again. If loading then fails with a different message, record that change instead of repeatedly retyping the same source.
Questions about this topic
Can a playlist URL contain a password?
Yes. Treat a URL with account parameters as private account information.
Should I replace http with https myself?
Use the exact supported address supplied by the service; do not guess a different endpoint.
