Failure to install CODE server: "An error occured during the request. Unable to proceed."

I am running nextcloud on a server with docker. The installation works good except for the fact that I’m unable to install collabora online CODE server. I think it’s a bug cause in previous docker installation I’ve made it worked perfectly.
When I click on “download and install” I get “An error occured during the request. Unable to proceed.”

Some specs about the machine it’s running on (in case they were needed):
OS: Arch Linux
Kernel: x86_64 Linux 5.4.57-1-lts
Disk: 14G / 1.9T (1%)
CPU: Intel Atom x7-Z8700 @ 4x 2.4GHz
RAM: 1399MiB / 1908MiB

Any idea how to solve this?
Thank you in advance

Did you ever resolve this issue? I’m having the same problem.

Anyone else have advice?

I was not able to solve this issue. I guess it might be solved in the next nextcloud update. The best alternative I found is to run collabora server in its own container. This is actually better and faster but requires some additional configuration.
