Why doesn't the Editor load? we do not want to deactivate Collaborative editing

Question

We recently started a project of upgrading from Confluence v5.6 to v6.1.
We hit issues in the 6.1 version when trying to publish a new page:
"Unable to communicate with server. Saving is not possible at the moment."
and
"The editor didn't load this time.
The connection timed out. If it happens again, speak to your Confluence admin. You may be using a proxy server that prevents WebSocket connections."

We are using Firefox and addressing the base URL of the installation, not frontended by any web-server (Apache), no URL redirection.

I turned Collaborative editing into "Limited" and it seems to be working.

But we want to keep Collaborative editing activated.

Can you help ?

Our replies just crossed. Thank you so much for following up. We will have to work on those guides!

Just saw on your ticket that the root cause was that Synchrony could not obtain a database connection until you added an argument to the synchrony-args.properties file.

If there is more about the case that you would like to share with the Community, feel free to update the thread in case it can help someone else.

It looks like we solved the issue with oracle.net.tns_admin=/opt/infra/tnsadmin

in file synchrony-args.properties.

previously we had errors related to Synchrony connection to the DB.

this does not look documented enough in the official guides.

Thanks
