Blank page and "loolmount incorrect user-name, other than 'lool'"

[gcommit]

Installed: Ubuntu 18.04 Nextcloud 21.0.3 PHP 7.4 Apache2 2.4.48 Collabora Online (richdocuments) 4.1.2 Collabora Online CODE 6.4.1003

When i start a Nextcloud, go to App Store and install the two Collabora apps, everything is fine. In the settings i see a "Connected"

But as soon as i want to open a document (or to reload my view of the document) the following output is generated:

with every try to open a document. It is running inside of docker container and the ports 80 and 443 are open.

What can i do? :(

This issue still exists with 6.4.1004.

[gcommit]

I started a new Nextcloud (22.0.0). Installed "Collabora Online - Built-in CODE Server" and "Collabora Online" in newest Versions

Instant blank page

[jman0815]

Same problem here!

[jhartmann44]

I've been searching for a solution, bug remains.

[gcommit]

Can anyone say something? At least "Hello" ?

[pwojcieszonek]

Collabora 4.2.0 not working either.

[manu-p]

Same here on: Ubuntu 18.04.5 NC 20.0.9 PHP 7.4 Apache2 2.4.29 Collabora Online - Built-in CODE Server 6.4.806 (too many bugs with 6.4.10!) Collabora Online 3.8.3

[gcommit]

any news here?

[gcommit]

Can please someone answer? Not being able to open files is kind of critical in such a tool ...

[gcommit]

HELLO?

[cornouws]

Sorry, no insight on my side. I assume that some that may have, are on holidays..

[gcommit]

So we ... wait?

[dmanea28]

Same for me. The editor opens, but I cannot save anything.

[EnderArchery]

Same problem

[craiq]

same problem! Is there any hint to fix this?

[gcommit]

unfortunately not .... sorry

[Michael-81]

I have the same problem.

Is there a solution?

[ssmid]

I edited proxy.php's launch cmd so that the AppImage is started with "--disable-lool-user-checking", but it gives me an error message "Option must not be given more than once: disable-lool-user-checking" and even segfaults from time to time. Pretty weird.

[ssmid]

After several reboots, server restarts, cleanups, ever changing logs, error messages and behaviour, I'm giving up. I was able to get an instance running one single time but the next time it's gone once more without having changed anything. I won't try anymore. Nextcloud is great; PHP, Javascript and web dev in general are certainly not. And AppImages seem to be just another mess.

[pawanrai9999]

Well this issue still exists in Nextcloud 22. I think we will need to run our own colabra online server. This is the only solution I can think of. I was able to work properly in one of my install earlier but I don't remember how I did it.

[mnn]

I hit probably same issue. I am running nextcloud in the official docker container, installed both plugins from store and since I saw some missing libraries in logs, I installed them manually in the container (I think libfuse2 and libcap2). It didn't help.

Aborting.

[fds2610]

on Nextcloud 22.2.8 the error message still exist, but it seem to have no negative symptoms. Doc/Xls opening and saving works.

[dg1sek]

On Nextcloud Server 24.0.6 this still occurs.

[juliennicouleaud]

It seems to work fine now! -> Collabora Online - Built-in CODE Server 22.5.702 and Nextcloud Office 6.3.1. (Nextcloud Server 24.0.6)

[Stef976]

I had the same problem with Nextcloud 25.0.1. If this can help, I resolved the problem by allowing TSLv1.2 in apache. I planned to only accept v1.3 but it seems that it's a problem for the app (curl errors in Logging).

[stephen304]

I was having this issue with nextcloud docker 25.0.1, CODE 22.5.802, NC Office 7.0.1 when it was working before on the same versions. My error is slightly different in that it says cool instead of lool

Oddly enough, I was able to fix this by navigating to /settings/admin/richdocuments and spam clicking the "Use built in code" radio button. When I had issues before, usually clicking this radio button once would often fix it, but this is the first time I needed to click it many times quickly to resolve the issue.

[martadinata666]

Is this ever getting fixed? Version 22.5.802 + Nextcloud 25.0.4 , I mean real fix, not just some random sudden work thing.

Also getting the coolmount incorrect user-name, other than 'cool' error on Nextcloud version 26.0.0 using the following deployment script: https://github.com/tomMoulard/make-my-server/blob/master/nextcloud/docker-compose.nextcloud.yml

But the strange this is on a different server using the same deployment file it works as expected :thinking:

[SysEngDan]

This is really discouraging that this still isn't working.

[timar]

Security: coolmount incorrect user-name, other than 'cool' – Aborting. is expexted, because it is a security check. In case of richdocumentscode the service is running by the user of the webserver (e.g. www-data) not by cool. I wonder why coolmount is invoked though, I would think it's a mistake, because we pass the --o:mount_jail_tree="false" in command line, when we start coolwsd. Having said that, I think it's still a red herring, because if bind mount fails, we fall back to link/copy, and it should work. It works for many people. So it's hard to tell what exactly should be fixed.
