It’s entirely possible. If the 2 domains are different, you should look into SNI routing using the TCP router instead of HTTP. With the tls.passthrough flag, encryption is kept intact until it reaches the second proxy.

Hey, I’m glad you got it working, yeah Continuwuity is still a drop-in replacement right now so all is good. I also did a drop-in a few months back with zero hassle at all. Most env vars and config options weren’t changed, but I redid my continuwuity.toml file just to be sure.
