I have okteto self-hosted running - it’s just lovely. thank you. working great for dev environments.

Now I’m trying to get the preview worfklows running based on [these instructions](https://www.okteto.com/docs/cloud/preview-environments/preview-environments-github/), but the workflow is failing. I’m at a bit of a loss here - I haven’t changed anything in the workfows (well, I did remove the -cindy-lopez suffix, but I don’t think that should be an issue right?)

any ideas!?

```auto

Cloning git repository 'https://github.com/parrot-time/fuji-service' branch 'otketo-previews'...

Hey @benjoldersma ! From the logs, it seems like the repo you are using is private?

If that’s the case, you need to do some additional configuration on your Okteto Self-Hosted instance to let Okteto clone private repositories.

With Github, there are two different options:

1. Add the cluster SSH key to your Github Account, and use an SSH URL instead of https. [This page](https://www.okteto.com/docs/administration/private-repositories/ssh-key/) documents how to configure that.
2. Create a Github App in your organization, and use Okteto to use it. [This page](https://www.okteto.com/docs/administration/private-repositories/github-app/) documents that process.

Hope this helps!
