# FAQ

## Do I have to use Docker?

Yes, that's how this project is packaged.

This makes it easier to support the project when I have control over the version of Nginx and NodeJS
being used. In future this could change if the backend was no longer using NodeJS and it's long list
of dependencies.


## Can I run it on a Raspberry Pi?

Yes! The docker image is multi-arch and is built for a variety of architectures. If yours is
[not listed](https://hub.docker.com/r/jc21/nginx-proxy-manager/tags) please open a
[GitHub issue](https://github.com/jc21/nginx-proxy-manager/issues/new?assignees=&labels=enhancement&template=feature_request.md&title=).

## I can't get my service to proxy properly?

Your best bet is to ask the [Reddit community for support](https://www.reddit.com/r/nginxproxymanager/). There's safety in numbers.

Gitter is best left for anyone contributing to the project to ask for help about internals, code reviews etc.

## When adding username and password access control to a proxy host, I can no longer login into the app.

Having an Access Control List (ACL) with username and password requires the browser to always send this username and password in the `Authorization` header on each request. If your proxied app also requires authentication (like Nginx Proxy Manager itself), most likely the app will also use the `Authorization` header to transmit this information, as this is the standardized header meant for this kind of information. However having multiples of the same headers is not allowed in the [internet standard](https://www.rfc-editor.org/rfc/rfc7230#section-3.2.2) and almost all apps do not support multiple values in the `Authorization` header. Hence one of the two logins will be broken. This can only be fixed by either removing one of the logins or by changing the app to use other non-standard headers for authorization.
