Unable to connect collabora online in local

While trying step by step tutorial couldn’t establish a connection via post method with HTML button. Getting response as above shown in image.
@pedro.silva can you have look into it.


there are 2 major differences in your setup to the tutorial:

  • use of IP address and not hostname
  • no https://

I think valid domain name and certificate are essential to make COOL work…

UPDATE: found a reference

Collabora Online uses WOPI protocol, which mandates SSL.
