MTA:SA error code

MTA:SA error CD20

A file the server sends you could not be downloaded.

How to fix it

  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.

These are the steps of the guide CD20: server resource download failed.

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.

About this code

Servers deliver their scripts, models and images over HTTP while you connect. The download can fail because of your connection, a full drive, security software, or the server's own download host.

A CD code appears when a connection to a server fails, is refused, or ends. Most of them carry a second line with the server's own reason. MTA's own documentation gives CD20 as HTTP download failure.
