I'm kinda out of the loop, I don't understand what's going on with Tesseract, could anyone explain it to me please :)
To connect your services to your domains, you can use Cloudflare Tunnels, its safe and it doesn't expose the IP of your servers.I'd reccomend this to get started : https://developers.cloudflare.com/tunnel/setup/ Also, subdomains are completly free!Good luck!
Nevermind ! I now understand, thanks to the comments !
