Clone VM with Collabora

Good morning,
I have configured a VM starting from the tech & me application with “collaboration” installed, and everything works correctly.
now having the need to create a second VM I tried to clone the working vm, clearly renaming the site name but when I try to open an online file gives me a WOPI error (Host WOPI not authorized. Please try again later and if the problem persists, report it to the administrator.).
can you help me?

thank you

hi, any ideas?
