Use Squarespace subdomain with jitsi server from hetzer


i am trying to install jitsi with not a lot of knowledge about servers or linux.

i managed to setup jitsi and its running on a server i have a domain at squarespace and added a subdomain for jitsi.
i also added @A and (the hetzner ip) on squarespace.

while installing jitsi meet i added the hostname . but when i go to i just get forwarded to the website and don’t see the jitsi server.

anyone any idea what i am doing wrong?
