[SOLVED] Cells: Origin is not allowed Access-Control-Allow-Origin


#1

Installation type: New install
Docker repository with docker-compose.yml, behind a Traefik reverse proxy
Debian 9
Pydio version: 1.0.2 2018-07-03

I manage to install Cells just fine via docker, but after the installation completes and then I login, I am getting some sort of further error. It seems to appear on pages that are loading external information (i.e. when setting up a user, the Country pick list will not load; on the Storage config, the error continually recurs at the bottom of the page.

The error that comes up looks like this:

Maybe I have some basic issue due to using Traefik? In caddy_errors.log I do see:
[ERROR 502 /] write tcp 172.18.0.5:8888->172.18.0.4:52496: write: broken pipe

My Traefik logs show no errors.


#2

I managed to fix this issue by going to:
Settings -> Configs Backends
and replaced the REST Endpoints address, which was internal to Traefik, with the external to the world equivalent

I had first tried setting the Replace Host header for S3 signature to the internal IP like it says in the docs, but this didn’t work.
