When I try to send a test message to a private (but previously public) channel, I get a 422 error. When I check the logs, I see this:

```json
Test provider failed {:error_key=>"chat_integration.provider.slack.errors.channel_not_found", :request=>"", :response_code=>"200", :response_body=>"{\"ok\":false,\"error\":\"channel_not_found\"}"}

```

This setup worked when the channel was private. I tried re-installing the Slack app and deleting the rules and recreating them. When I use @username rule or a public channel that seems to work well.

Double check you have configured all the “scopes” listed in the plugin topic: [Set up Slack notifications using the discourse-chat-integration plugin](https://meta.discourse.org/t/set-up-slack-notifications-using-the-discourse-chat-integration-plugin/66730)

Do slash commands work from the private channel? If so, try creating a rule using those, and see whether it appears in the Discourse admin interface.

All scopes are configured as required by the docs.

`/discourse watch private-category` works from the private channel. I can see the rule get created in Discourse.

When I try to send a test message from Discourse with an ID of a topic in the private category, I get the 422.

chat integration discourse username is `system`

Temos o mesmo problema.

Curiosamente, as notificações para o Slack funcionam para o canal do Slack recém-criado, mas não para o antigo.
