So i have a pfsense gateway, and 2 vms behind it.
I have nextcloud in one, and CODE in the other.
I have configured everything and it worked for a week or so with no problems.
Now, i cannot edit documents if i access the instance (nextcloud+code) from another location except one in particular (where i work).
So the pfsense gateway has a public ip. There are no direct connections to those vms.
So if i try to open a document from home for example, the editor does not load.
If i try this from the workplace (on the same public URL), it works.
This is the haproxy config on the pfsense gateway

I simply dont understand why is would work in one place and not another, since im using the same public hostname.
Im thinking that maybe haproxy has something to do with it, but i cannot think of anything.
Has anyone ever had a situation like this ?

So from what i can see on the clients where its not working the bundle.js file is incomplete.

Yeah. This is really strange.
Now this does not work from anywhere.
The thing is i installed it again from scratch on a container, and on a full vm, on ubuntu 20.04 and 22.04, and it has the same behaviour.
Is there anything i could check or do on my side ?

yes if you could paste here some logs that would be helpful. Logs from web dev tools → console in your browsers and also the logs from nextcloud available from admin account \> settings \> logging

So this would be from the collabora admin console:

This would be from when accesing a file from nextcloud:
> bundle.js:1
>
> ```
> Uncaught SyntaxError: Unexpected end of input (at bundle.js:1:421346)
>
> ```

In both cases collabora seems to generate incomplete js files. So admin-bundle.js and bundle.js is incomplete.
In nextcloud i dont get any errors when opening the file.
So it seems that the problem is just the fact the those js files are incomplete.
You said that you remember something about a cache problem with the vue app. Is there any way to force this ?
EDIT:
I also see this in the logs when accesing the admin console:
> WRN client - server version mismatch, disabling browser cache. Expected: deaf0cb| wsd/FileServer.cpp:510
and this when accesing a document:

PS: collabora is running in a container on ubuntu 20.04, but i have the same problem when running in a full vm.

So im not sure if this could be a problem, but collabora is running behing pfsense and haproxy. And from what im seeing in the dev tools in chrome is not establishing the websocket connection.
But it weird, because im passing everything from the domain to the collabora container.

I have this exact same issue and setup. pfsense with haproxy, nextcloud in docker and collabora in docker as well. I have tried many combos of configurations from many posts.
The debug console says the same exact error as above… when I open bundle.js from the link in the debug console in chrome it is indeed cut short.
@fxandrei did you ever get this figured out?

Im not sure what i could try.
For now i have given up on using collabora code.

What are you using instead? I’d like to have an online office solution.

Im not using anything right now. I just using the nextcloud client, installed on my pc, and whenever i need to edit anything i access the documents from windows explorer.
Im thinking of using online office server, but havent managed to configure everything yet.
Edit:
The only other solution to this would be onlyoffice, but that has a limitation of the number of users using the same document . I think its 20.
After that, the document is readonly.

So i ended up changing the configuration a little bit.
So im not going through haproxy anymore. Im doing pure NAT now.
I have configured the collabora vm to use SSL (so no more ssl termination, so i have the cert in that vm).
Now everything works.
Im not sure why i had that problem with the incomplete js files.
The only thing i can observe is that when it goes through haproxy it does not establish the websocket connection, and i dont know why, because i have been using different application that use websockets and they work.
Anyway, not it works.
