Error codes
When something fails, Zapline shows a code such as ZL-AUTH-401 and who most likely caused it. Zapline includes no channels: streams, accounts and guides come from the source you added, so many problems can only be fixed by that provider.

ZL-AUTH-401 Login not acceptedLikely cause: provider
Your provider's server did not accept the username or password. Only the provider can confirm the correct details.
What to do: Check them with your provider, then update the source.
ZL-AUTH-403 Access refused by the providerLikely cause: provider
The provider's server refused the request. Providers do this for account, region or IP address reasons.
What to do: Ask your provider whether your account or network is allowed.
ZL-ACCT-EXPIRED Account expiredLikely cause: provider
Your provider reports that this account has expired. Account dates are kept by the provider.
What to do: Renew the account with your provider, then try again.
ZL-ACCT-MAXCONN Too many connectionsLikely cause: provider
Your provider allows a limited number of simultaneous streams and all of them are in use.
What to do: Stop playback on another device, wait a minute, then retry.
ZL-HTTP-404 Stream not foundLikely cause: provider
The provider's server does not have this stream. The channel may have been moved or removed on their side.
What to do: Refresh the source. If it stays, ask your provider about this channel.
ZL-HTTP-5XX Provider server problemLikely cause: provider
The provider's server reported an internal problem. It is not caused by your device or by this app.
What to do: Try again in a few minutes.
ZL-NET-DNS Server name not foundLikely cause: network
This device could not look up the server's address. The address may be incorrect, or your network's DNS is not answering.
What to do: Check the server address, or switch between Wi‑Fi and mobile data.
ZL-NET-TIMEOUT Server did not answer in timeLikely cause: network
The connection to the server timed out. The network or the server is too slow or unreachable right now.
What to do: Check your connection and try again.
ZL-NET-TLS Secure connection failedLikely cause: network
A secure (HTTPS) connection could not be set up. The server's certificate may be invalid, or something on the network is interfering.
What to do: Try another network. If it keeps failing, ask your provider about the server certificate.
ZL-NET-OFFLINE No network connectionLikely cause: network
This device has no usable route to the server. This is a network problem, not a problem with the playlist.
What to do: Check Wi‑Fi or mobile data, then retry.
ZL-NET-REFUSED Server refused the connectionLikely cause: network
The server is reachable but is not accepting connections on this address or port.
What to do: Check the address and port, or try again later.
ZL-CODEC-AUDIO Audio format not supportedLikely cause: this device
This stream's sound uses a format this device cannot decode. The stream itself is fine.
What to do: Try another audio track, or play it on a device that supports it.
ZL-CODEC-VIDEO Video format not supportedLikely cause: this device
This stream's picture is beyond what this device can decode (format or resolution).
What to do: Choose a lower-quality version of the channel if the provider has one.
ZL-STALL Stream stopped sending dataLikely cause: provider
The connection is open but the provider stopped sending video. This usually comes from the provider's side.
What to do: Retry. If it keeps happening, tell your provider which channel it is.
ZL-FORMAT Unrecognized stream formatLikely cause: provider
The server returned something that is not a video stream (for example a web page). This is decided by the provider's server.
What to do: Check the address, or ask your provider for the correct link.
ZL-PLAYLIST-EMPTY Playlist has no channelsLikely cause: provider
The address works, but the list it returned is empty. The provider or the file has nothing in it.
What to do: Check that the address is the one your provider gave you.
ZL-PLAYLIST-INVALID Not a valid playlistLikely cause: provider
The address returned something that is not a playlist, such as a login page. This is decided by whoever hosts the link.
What to do: Check the address, or ask your provider for a new link.
ZL-PLAYLIST-STREAM This link is a stream, not a playlistLikely cause: provider
The address plays one channel (a video stream) instead of returning a channel list.
What to do: Use the playlist (M3U) link from your provider, usually ending in get.php or .m3u, not a channel link.
ZL-EPG-INVALID Guide data could not be readLikely cause: provider
The program guide file is not in a format this app understands. The guide comes from the address you set, not from the app.
What to do: Check the guide address, or ask your provider for the correct one.
ZL-EPG-NOMATCH Guide does not match channelsLikely cause: provider
The guide loaded, but its channel IDs do not match your channels, so no programmes can be shown.
What to do: Match channels to the guide manually, or ask your provider for a matching guide.
ZL-UNKNOWN Something went wrongLikely cause: app
This problem did not match a known cause, so it may be in the app.
What to do: Retry, or copy the diagnostic report and send it to support.
