Hi all,

So im follwing this guide https:// nextcloud. com/ collaboraonline/ to get collabora working on my owncloud.

now my domain for owncloud is data.dingit.dk and collabora is office.dingit.dk

I have my docker running:

0369e5983530 collabora/code “/bin/sh -c 'bash sta” 24 hours ago Up 24 hours 127.0.0.1: 9980->9980/tcp peaceful_fermat

Here is the apache conf file

<VirtualHost *:443>
ServerName office. dingit .dk:443

SSL configuration, you may want to take the easy route instead and use Lets Encrypt!

ServerAlias office. dingit. dk

I have tried to disable the firewall
I ave tried to disable the apparmor
I have tried with the Collabora app in nextcloud to both use :443 and :9980 no change. I evne tried without using any ports and just the URL office.dingit.dk

I chose lets encrypt for SSL but im not using ACME. I just followed the guide from lets encrypt on ubuntu 16.04. but from the looks of the conf file it looks to right.

My problem is i keep getting this error when i open a .docx file in owncloud:

Collabora Online: Cannot connect to the host “https:// office. dingit.dk:443”. Please ask your administrator to check the Collabora Online server setting. The exact error message was: cURL error 7: Failed to connect to office.dingit.dk port 443: Connection timed out

can anyone help me here?

don’t mind the spaces in the URLs. as a new user im only allowed to post posts with two links in them…

see the troubleshooting section - did you start docker with the right URL? Tripple-check, it did cost me a full day before I found out that that was the problem :wink:

Hi Jospoortvliet,

Sorry for the slow respons :slight_smile: but i have been a busy little bee :slight_smile:

Yes i did tripple check this specifik thing and i did remember you mention it in your youtube video.

But just to be clear in my case this would be line right?

docker run -t -d -p 127.0.0.1:9980:9980 -e “domain=data.dingit.dk” --restart always --cap-add MKNOD collabora/code

since my nextcloud server is data.dingit.dk - or should it be domain=data.dingit.dk

I found the problem. And it had nothing to do with nextcloud. I have a edge firewall which was not NATing port 9980 to the nextcloud server… which you need :slight_smile:

dear sir how did you solve your problem can you show a little bit please
many thanks

i can try…

my nextcloud server was behind a firewall. This firewall had opend port 443 so that i could access my nextcloud servers webinterface and with my windows client.

but i hadn’t opend port 9980 which collabora is using and so my firewall was blocking. adding a allow rule for port 9980 solved my issue
