Collabora - The requested URL /browser/dist/admin/admin.html was not found on this server

NethServer Version: 7.9.2009 (final)
Module: Collabora and Nextcloud-Office

I’ve followed the steps in this collabora howto.

I’ve gone through this community post and this post

I’ve also configured my coolwsd.conf script to replace all instances of http://127.0.0.1:9980 with https://collabora.rennco.cloud:9980. I’ve set my admin username and password for collabora in the command line.

I’ve entered DNS CNAME records for collabora and nextcloud-office.

I’ve updated my Letsencrypt certificate to include collabora.rennco.cloud and nextcloud-office.rennco.cloud.

I’ve opened TCP/UDP port 9980 in the shorewall firewall configuration.

I’ve restarted all associated services. I’ve even restarted my server.

I have not been able to access the admin page in any browser. I get ‘requested url not found’.

Additionally, when I try to save https://collabora.rennco.cloud:9980 in the ‘Use your own server’ field in the Nextcloud Office configuration (logged in as the Nextcloud admin in a browser), it spits back ‘could not establish connection to the Collabora online server.

I’m at a loss at this point. Any suggestions on where to go from here? Thanks.

Please share your config, maybe there’s an error:

config show coolwsd

Maybe it helps to reconfigure Collabora:

signal-event nethserver-collabora-update

Did you update Collabora? Which version do you use?

rpm -q coolwsd

Why? This usually isn’t necessary and may break it. Please remove the changes. The Collabora admin console should work out of the box.
Collabora uses a reverse proxy to 127.0.0.1:9980 in /etc/httpd/conf.d/zz_collabora.conf so the admin console is reachable at https://collabora.yourdomain.com/browser/dist/admin/admin.html

No port needs to be opened for Collabora.

That shoudn’t be needed, it’s already preconfigured.

coolwsd=service
AllowWopiHost=nextcloud-office.rennco.cloud.com
VirtualHost=
status=enabled

I changed the config file back to 127.0.0.1. /etc/httpd/conf/coolwsd.conf below:

# Apache2 reverse proxy configuration for Collabora Online
# Internet <-- SSL --> Reverse Proxy <-- No SSL --> coolwsd
# Make sure that you enable the following Apache2 modules: proxy, proxy_wstunnel, and proxy_http.
# Create a virtual host for Collabora Online and include this configuration file.

  # keep the host

I've already done `signal-event nethserver-collabora-update`.

Version = coolwsd-21.11.0.5-1.el7.x86_64

You don’t need to create /etc/httpd/conf/coolwsd.conf because there’s already /etc/httpd/conf.d/zz_collabora.conf.
Just follow the documentation, there’s no need for additional configuration.

You didn’t define the VirtualHost but it’s required as explained in the docs.

config setprop coolwsd VirtualHost collabora.rennco.cloud
signal-event nethserver-collabora-update

You defined AllowWopiHost but it isn’t needed if Nextcloud and Collabora are running on the same server.

To remove it:

config setprop coolwsd AllowWopiHost ''
signal-event nethserver-collabora-update

Thank you for the help, Markus. I didn’t create the coolwsd.conf file.It was put there when I installed collabora. I’ve renamed it to conf2 so it’s out of the picture. The zz_collabora.conf file is present also. I did all the steps you told me to and still nothing. However, now when I try to access the admin page in a browser, I get server not found rather than url not found. I can ping collabora.rennco.cloud successfully. Here’s what config show coolwsd shows now:

coolwsd=service
    AllowWopiHost=
    VirtualHost=collabora.rennco.cloud
    status=enabled

UPDATE: I rebooted my nethserver and now I can access the coolwsd admin site. However, when I try to open a Word doc in Nextcloud, I get ‘Document loading failed. Failed to load Nextcloud Office. Please try again later.’

UPDATE: Followed your input on this post and did the richdocuments update, then signal-event nethserver-collabora-update and now I can open Office documents! Excellent! Thanks for all of your input, Markus!
