MTA:SA fix

CD20: server resource download failed

A file the server sends you could not be downloaded. Connect again first. The line after CD20 tells you which of the other steps applies.

The message

Error downloading requested files

Codes on this page: CD20

Steps

  1. Connect again

    Close MTA, open it again and connect once more. On CIT, connect with mtasa://s2.cit.gg:22003: connecting directly also helps when a file failed to download last time.

  2. Try two MTA settings

    Press ESC, open Settings, then Advanced. Set Single connection to On and Browser speed to Very slow, then connect again. MTA’s team has suggested both for download trouble.

  3. If the message is about a slow transfer or a timeout

    Only when the message says the transfer was slow or timed out.

    Pause other big downloads on your connection, then connect again.

  4. If the message says a file could not be written

    Only when the message says writing the file failed.

    Check that the drive MTA is on has free space, make room, then connect again.

  5. If the message says the file is missing or gives a server error

    Only when the message names a missing file, a bad address or an HTTP error from the server.

    That is on the server’s side. Send the server’s staff the full message and the name of the resource. Reinstalling GTA will not fix it.

  6. Still unclear: try another server

    If other servers download fine, report it to the server that fails. If every server fails, take the full message to MTA’s client support.

    Careful: Do not delete all downloaded resources or turn off your firewall as a first try.

Worth knowing

CD20 alone does not say which of these it is: the line after it does.

Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.
