PLEASE help us help you by writing a good post!

- we need to know your netlify site name. Example: `gifted-antelope-58b104.netlify.app`
- DNS issues? Tell us the custom domain, tell us the error message! We can’t help if we don’t know your domain.
- Build problems? Link or paste the FULL build log & build settings screenshot

The better the post - the faster the answer.

Hi!

I’ve 4 sites which need to access a submodule (also a Netlify site), but it’s impossible.

I added `git submodule update --remote --recursive` to the build command, copied the public key to BitBucket and… Nothing worked. I recreated the public key, which broke the builds, updated the keys in both repositiories and… Still nothing.

What else I need to do?

One of the sites is `vigilant-newton-485906`.

Thank you!

> Last reviewed by Netlify Support on December 2022 The link from your repository to our service only authenticates us against the “main” repo that you first configured, and won’t automatically allow access to submodules even if they also belong to you and you’ve granted Netlify access to those repositories. In case your submodule is public, you can change the URI schema for it to start with https://, and it should work without further adjustment (so, in .gitmodules, change git@github.com… to h…
