# Troubleshooting

> Start here when something misbehaves.

The three problem families, in the order they usually occur:

<CardGroup cols={1}>
  <Card title="Connecting a channel fails" href="/general/troubleshooting/oauth-connect">
    Errors during the platform approval flow, and channels that immediately
    demand reconnection.
  </Card>

  <Card title="A post did not publish" href="/general/troubleshooting/publishing">
    Reading the error state, and the platform rejections behind it.
  </Card>

  <Card title="Uploads and media" href="/general/troubleshooting/uploads">
    Files that will not upload, and video the platform refuses after upload.
  </Card>
</CardGroup>

## The two facts that resolve most tickets

**Account types gate publishing.** Instagram requires Business or Creator;
Facebook requires a Page; several platforms restrict by account kind. A channel
that connects but cannot publish is almost always this — see
[platform reference](/general/platforms/overview).

**Tokens expire by design.** Platforms cut tokens on a schedule, and
immediately when you change your password there. Reconnecting from the channel
menu is routine maintenance, not a fault.
