Error connection Nextcloud to OnlyOffice

Docs
1

I have installed OnlyOffice using the helm charts on an OpenShift clusters as described here: GitHub - ONLYOFFICE/Kubernetes-Docs: ONLYOFFICE Docs for Kubernetes

Containers are all running. Now I’m trying to connect Nextcloud (running on the same cluster) to OnlyOffice but I receive the following errors:

In the Nextcloud UI:

Error when trying to connect (Error occurred in the document service: Error while downloading the document file to be converted.) (version 9.2.1.8)

Nextcloud container logs:

... "message":"getConvertedUri on check error","exception":{},"CustomMessage":"getConvertedUri on check error"

Converter container logs:

[ERROR] [check_2084142047] [userId] nodeJS - error downloadFile:url=https://redacted/apps/onlyoffice/empty?doc=redacted;attempt=3;code:SELF_SIGNED_CERT_IN_CHAIN;connect:undefined Error: self-signed certificate in certificate chain

We are using a self-signed certificate and I have thus already set the ENV variable “USE_UNAUTHORIZED_STORAGE” on the docservice and converter container but that hasn’t changed anything.

Hey @michizubi-SRF, :wave:

Thanks for the detailed description and logs — it’s clear you’re running a proper Kubernetes/OpenShift setup.

To use the editors in a cluster environment like this, you need a valid license for ONLYOFFICE Docs Enterprise Edition or Developer Edition. The community (free) version is intended for smaller-scale usage (up to ~20 simultaneous connections) and is not officially supported for Kubernetes clusters.

If you already have an Enterprise/Developer license, I strongly recommend contacting the official support team directly — they can help you troubleshoot the issue.

You can reach them here:

Let me know if you have a license and I can point you to the right support channel again. Otherwise, feel free to ask anything else!
