Is Collabora Online cannot normally use with chroot Linux boot?

I use the Collabora Online Appimage for ARM64. The Liinux is boot by chroot.
When I use nextcloud richdocument add-in to connect to the CODE Server, It will notify me cannot connect.

I have the same probrem… but i don’t know witch of both sides it’s blocking the connection… chroot or Collabora… i have the intuition that chroot its blocking the connection to the subdomain in the same server where i had installed the collabora server
