I am thinking of trying caddy, but I don’t think it’s the issue. As I said, a curl command works fine, and I also have a peertube instance that takes way bigger files just fine.

Thanks, I try over there

That’s what I tought, but both cinny and element web have this issue and it sounds like people should be able to go up to 2GB.

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.
