Seafile link with collabora online problem

Hi Seafile team,
In past few days, i just got a problem with connection between Seafile and collabora office.

Collabora was deployed on docker and following is the process of verifying success.
https://seafile.llycloud.com/f/46aabdb84f5549e78abd/

And then i followed manual to edit configuration and restart server.
https://manual.seafile.com/deploy/libreoffice_online.html

Unfortunately, the connection between Seafile and collabora are not successful because of unknown reasons.
There is debug information of document view web page:

So personally i guess this problem happened with this error page but i don’t know how to fix it out.

Hope someone can give me some suggestion to solve this problem.

Thanks
Akide Liu
