Start by reproducing the failure from Files with an .ODT file, comparing the configured Collabora demo server with the built-in CODE server. Check the URL produced in each case and use the expected /index.php/apps/files?dir=/&openfile=... form as the completion criterion; the issue reports no useful Nextcloud or browser logs.
