Yeah, I can’t find either of those settings in the configuration docs and I wasn’t just sending images.

How would I do that? The curl command already works and the service is being handeld by the reverse proxy, which depends on the domain name to pass the requests correctly. Even if I succeeded, element-web is configured to send the file to the domain name, not the local address.

The idea is to have one nginx container responsible for the tls handling and request distribution (I have more than one service running on the device) and the other for actually handling the request. It keeps things organised.
