Failed to get LoKitDocument instance

I followed install instruction, and after several issues, I hit this one I can’t solve.

But nobody really answered thoses question, that’s why I’m opening a new thread.

Let me know how we can solve that, and how I can help on the process! Thanks!

After updating the Collabora Docker container and rebooting the system, I again have the same problem. Before, it somehow had magically disappeared after a few days of debugging and testing. But it’s back again with the same error as @pierreozoux has. I’ve got the richdocuments App enabled globally, Apache redirects HTTP to HTTPS for all VHosts and the new ProxyPassMatch rule is in my Collabora VHost. It would be awesome to find a solution to the problem.

Hi @pierreozoux,

I just updated the Richdocuments/Collabora Online App in Nextcloud from 1.1.7 to 1.1.9, whic fixed the bug for me. Awesome, now Collabora Online works again in my Nextcloud installation.

By the way, I still use the Collabora Online Docker container and I don’t use aufs as storage driver. In Debian Stretch (with Linux kernel 4.7), AFAIK Docker uses the overlay storage driver per default. And apparently that works well with the Collabora Online Docker container.

Probably this topic should be closed now that the issue has been resolved?

Still no luck…

I’m now using latest docker image and latest collabora application (1.1.10).

I get a simple and new document, and when I click on it, the spinner is just spinning.

Here are some relevant logs from the server:

Here is my collabora server:

If anybody has a working nextcloud instance, I’d be glad to test it against my collabora to see if the issue is coming from collabora or nextcloud.

It looks like collabora has trouble to contact the Nextcloud instance. Do I need some specific configuration if I run behind nginx?

While finally everything worked out well under Debian 8.6 with kernel 4.7, since my update to NC 11b2 collabora stopped working. And unfortunately I couldn’t find anything interresting in the logs. I then decided to stop the docker service, because there were massive performance issues that slowed down the entire VM.

It’s a strange thing Collabora with docker on Debian… Anyway, as I don’t really use Collabora to much, I’ll wait for the final NC 11 Release, before I’ll do any further research. I’m just too tired of it :wink:

I got these segfaults as well (on Debian Sid/nginx), updating the kernel (from 4.1 to 4.8) solved these problems. The app now works as intended. In other words, try again after updating the kernel to 4.something_recent.

Thanks for your comment @Yetangitu but I run coreos, and I’m already at kernel version 4.7.3.
I don’t think the issue is from there.

I’ll try this week to track down further. I have the feeling that my HAProxy -> Nginx -> Nextcloud is causing some issues. I guess some http doesn’t go through and collabora is complaining. (But this is just a wild guess)

For those striking this issue, i’ve found that stopping the Docker container then starting it again resolves the issue.

This can be accomplished with the “docker stop” and “docker start” commands (not “docker run” - that’s for the first initialization of the container).

If your circumstances were the same as mine, your container will, on first boot anyway, immediately spawn a good 8 or so loolkit processes, which generate quite a bit of load until they finish starting up and settle down. Subsequent starts don’t do this, and work normally.

I ran into this by accident when editing /etc/loolwsd/loolwsd.xml to enable a higher level of logging (it defaults to warning - if you’re still running into this issue then try setting it to info, I wouldn’t recommend debug as it includes the raw content of images in that mode, giving you a massive binary mess which is impossible to sort through).

Ok, I just changed to info, so I have a lot more to debug :slight_smile:
But I still don’t see the issue:

I’ve the same problem. Im using Debian Jessie with Kernel 4.8 but still no luck…
Any other Ideas?

Ok, tried again, and this is not coming from my “weird” HAProxy setup. Just tried with plain nginx in front, but still no luck…

Is anyone running collabora in CoreOS ?

Hi everybody.
New on this kind of docker app setup (maybe because I am not really a Docker fan).

I set up a collabora code docker container on my KVM server running Debian Stretch (with aufs-dkms support), and Docker running in overlay mode.

After an afternoon configuring my collabora online setup (server version: 1.13.0) and nextcloud collabora client (1.1.25), i’ve still a problem loading a document.

If you have any information about this problem, I am interested.
Thank you all !

Docker wasn’t very keen at first but actually become to like it.

docker ps -a #list all containers.
docker stop [container-id] #stop container
docker rm [container-id] #delete container
docker images #list all images
docker rmi [image-id] #delete image
docker exec -i -t [container-id] /bin/sh #run shell inside container
docker logs [container-id] #view log
docker info #environment setup

Check your DNS on the server and inside the container.
nslookup example.com
Check your certs on the server and inside container.
openssl s_client -connect example.com:443

Hi,

Thank you for your tips !

I’ve checked, all my certs are signed by a recognized CA. openssl both inside docker container and VM say cert is valid.
DNS resolution works too. It’s weird.

Also tried to wipe all docker images, containers, fs et rebooting service and reinstalling collabora using tutorial, same issue…

Dunno sorry, only thing I can say is that I failed with aufs support and it worked with device-mapper.

docker info will tell you if you are using device-mapper or aufs.

It complains about device-mapper but it does work.

My noob tutorial by a noob, maybe give it a go.

As you can see, I have overlay, and I can say that it is not working.
Would be nice to have this in the documentation :slight_smile:
