Stop Jitsi From redirecting to sub domain on HTTPS

Hi All,
I am running jitsi under a subdomain with other redirects, working fine, however when I added a new subdomain which I will proxy back to my home network with my secure tunnel (HTTP works fine).

Q. How do I stop jitsi from redirecting the new subdomain to jitsi sub domain under HTTPS, I just need the new subdomain to be ignored by jitsi and allow my caddy install to assign its own SSL?

Any advice greatly welcomed.

Small update when I run certbot on the domain I get the below error
