Confluence API error CONFLUENCE_FORBIDDEN

[sattler]

I tried to connect Confluence to Slack. While I had an INVALID_CSRF issue that got resolved thanks to this thread, I now get a new error message.

Confluence API error
Error code: CONFLUENCE_FORBIDDEN

1. I removed the Confluence App from Slack.
2. I switched to the Confluence Page and clicked on Slack.
3. I confirmed that the I want to install it and grant access.
4. I switched to Slack and type in /confluence connect to connect to my confluence page.
5. I click the button "Log in" in Slack
6. On the landing page "Connect your Confluence Cloud and Slack accounts", I clicked the button "connect accounts"
7. I confirmed the layer to grant access.
8. I got the error CONFLUENCE_FORBIDDEN

Has anyone an idea how to solve that?

Thanks,
Tobias

I tried this a couple of times, and it always ended with an error. Then I found this link: https://support.atlassian.com/confluence-cloud/docs/use-slack-and-confluence-together/

There is a link to install Confluence for Slack on this site, and after confirming that process, the App is successfully installed.

I dunno why, but it is working now.

I rejoiced too soon. It seemed to work, but in Slack, I got the message, "There aren't any subscriptions for this channel. To add one, type /confluence connect <page-or-space-url>."

If I use that and add the space I want, I get a new error. Unfortunately, not very meaningful. Does anyone have an idea how to fix that?
