Hello everyone, I'm encountering an issue with my Express server snap where HTTPS requests are failing when accessing the /express-server endpoint using the URL https://192.168.0.205/express-server. However, accessing https://192.168.0.205:9595/express-server works fine (see screenshots below). It's important to note that I'm not using Unix sockets and I am using a reverse proxy to port 9595 (defined in the package assets file). Additional Info: Build environment: Ubuntu 22.04 Snap base: core22 CtrlX CORE X3 (with core 22 app installed) CtrlX Works version: 1.20.5 I'm using self-signed certificates to grant HTTPS access. Additionally, when I hosted the server as HTTP, certain view elements load, but others do not due to HTTP/HTTPS conflict. I've also observed that accessing https://192.168.0.205/express-server throws a 502 Bad Gateway error. And a message that ''The app is currently not available'' is being rendered . At the end, my aim is to maintain HTTPS for all requests, ensuring a secure connection throughout. Screenshots: package.assets File: {

} catch (error) {

}
}
startServer(); Any insights or suggestions on how to troubleshoot and resolve this issue would be greatly appreciated. Thank you! Solution: Issue was resolved by switching the protocol from HTTPS to HTTP, mofifying the static file paths and creating a directory called express-server.
