Onlyoffice not working properly in Nextcloud.

I have installed the Onlyoffice app inside the Nextcloud in a Raspberry Pi 4 with the dietpi software.

I put the address of the document server as follows:

"Server settings
ONLYOFFICE Document Service Location specifies the address of the server with the document services installed. Please change the ‘’ for the server address in the below line.

Document Editing Service address"

The error that I receive is this one:

"Error when trying to connect (Client error: GET resulted in a 404 Not Found response: <?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “htt (truncated…) )”

Could anyone help me?

Thanks in advance!


I don’t think this is something we can help with. As you can see, your application is trying to connect to a website

Client error: `GET` resulted in a `404 Not Found`

And this website is not available. I see you adjusted the original post. however i tried with the real link and got the same message 404

Edit: is reachable. so it’s your sub-folder healthcheck that did not seems to exist

Thanks for your answer.

So which address should I use to run onlyoffice in nextcloud? Both are installed in the same raspberry pi.

Thanks in advance!


maybe you could have a look to this guide


I installed onlyoffice from the nextcloud menu, but I am not really sure about if it is working properly. If I access I received a “404 Not Found” message.

Any suggestion?

I guess you would need to install OnlyOffice application as well. Activating the app within NextCloud is not sufficient.

Hi, I downloaded and activated it from inside the nextcloud menu. Is this the wrong way to do it?

The app is just a frontend with Nextcloud integration, but for this to work you need to install the OnlyOffice server outside oud Nextcloud as well. Please check the Nextcloud forum or 3td party guides for this, as at least I have never really read into this topic.

yes, you would need to install OnlyOffice server as well. One variant you can find on the link below.

or this community guide


I just saw that “Nextcloud Hub” has an internal OnlyOffice server included, based on PHP, which does not require an external server anymore. It is limited a bid, 20 concurrent users max and such, but at least it makes setup much easier.
