it looks you are running Nextcloud without valid domainname and TLS, which are mandatory to use WOPI protocol (Collabora). Please configure Nextcloud and Collabora with https and valid TLS certificates and try again.

6

But you can use collabora online (only from inside your 10.x.x.x network) install if you install the nextcloud app ‘nextcloud office’ and set url/port to your collabora online server in the settings section ‘office’, for example to ‘http://10.168.178.2:9980’. Do not forget to disable certificate check one line after your ip address entry.

Of course works only with a additional collabora online server.

As example here to do this with docker-compose json

ksnip_20220722-133109

7

It’s possible to run both Nextcloud and Collabora without direct assigned TLS certificate behind reverse proxy which terminates TLS (offloading). WOPI protocoll involves 3 parties: user client, storage system (Nextcloud) and and Office Server (Collabora) where all components need connections to each other - which makes it hard or impossible to operate without proper TLS setup. I definitely recommend you to setup proper TLS configuration and use public names for every connection…

very good thread with lot of references

8

Yes of course, i am using exactly this config with TLS terminating in a docker environment behind a reverse proxy and you’r absolutly right.

9

try it with TLS still having same issue

10

where can i find this json file path please

11

still having same issue collabora gives ok with http but with https it give ERR_SSL_PROTOCOL_ERROR
i’m using apache reverse proxy and yes i installed cert for the collabora vhost, anyone can help?

12

Okay if you do so you should have a wopi discovery xml file if you point to the URL

https://“your-collabora-code-server-URL”>/hosting/discover

e.g. like this

ksnip_20220725-154902

(partly)…
Do you?

If not, your apache reverse proxy conf fails

13

it show unsecure connection.
yes, it looks issue on apache reverse proxy but i did the configuration and added the certificate as well, can you please help me with this?

14

Put your apache config here to investigate …

15

just a note I’m using nextcloud and collabora docke in same VM

# The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. ServerName collabora.xyz 
    Options -Indexes
    # Encoded slashes need to be allowed
    AllowEncodedSlashes NoDecode

it give me :

The requested URL was not found on this server.

17

when i tried https://collabora /hosting/discovery it works , but still have the same issue document keep loading then fails

18

image

19

Okay, same apache config here but i do NOT have set the “Options - Indexes” value.

In the docker config for your collabora/code vserver do you set the ENV “domain” to your nextcloud FQDN? And again, https://“your-collabora-code-server-FQDN”/hosting/discover show similar of mine above?

And you have another working https FQDN for your nextcloud vserver, right?

20

this is how i run the docker
docker run -t -d -p 9980:9980 -e “domain=nextcloud.x.yz” -e “server_name=collabora.x.yz” --restart always --cap-add MKNOD collabora/code

and yes https://collabora/hosting/discovery works and shows xml

21

No, “https://nextcloud.x.yz/hosting/discovery” MUST work.
