Good day everyone!

I created a Collabora server which our NC servers use with NC Office

After a server restart of Collabora, NC Office can still successfully detect the Collabora server but opening documents lead to an error

When I login in to browser/dist/admin/admin.html, the issue is resolved

What causes this little quirk and whether there’s a possible workaround

Additional info:  
Collabora 23.05.5.4  
NextCloud 27

Any insight would be appreciated 🙂

Hey @Lulina. Welcome to the forum + thanks for the post!

I’m going to move this to the “Installation & Configuration” section of the forums, where others might be able to find/help you better. 🙂

Okay, I’m a little confused.

Let me see if I’m understanding correctly:

- You are running Nextcloud.
- You installed Collabora Office (or Nextcloud Office?).
  - Which one?

- You can get to `/browser/dist/admin/admin.html` successfully, but can’t open documents.

**QUESTION #1:** Did you follow any installation instructions? Can you link them here?

There is also a helpful topic over at the Nextcloud forums which might have some Nextcloud\<-\>Collabora troubleshooting tips too:

- [Nextcloud Forums: “Collabora integration”](https://help.nextcloud.com/t/collabora-integration/151879)

Perhaps one of their debugging steps might help you.

**QUESTION #2:** Can you tell which exact error appeared?

Hi there Tex

Thank you for you time 🙂

We have several self hosted NextCloud servers  
On those servers the app, Nextcloud Office 8.2.3, is installed and configured to connect to the Collabora server ie [https://domain.com:9980/](https://domain.com:9980/)

Before I access /browser/dist/admin/admin.html, documents won’t open. **After** I login with the admin credentials, the documents open and can be edited again.

[Here you go](https://www.collaboraoffice.com/code/linux-packages/), this was installed on Ubuntu 22.04

> **QUESTION #2:** Can you tell which exact error appeared?

Unfortunately I did not document the errors, total oversight on my part. They were along the lines of “Failed to load document” and “reverse proxy”

Thank you for the troubleshooting link, I will have a read through

Hope to hear from you soon 🙂
