For feature suggestions, describe the result you would like to achieve in detail:

I would like Onlyoffice to convert files correctly and open them in NextCloud. Unfortunately, now when Onlyoffice is enabled, NextCloud freezes and does not respond after adding new files.

For bug reports, provide the steps to reproduce and if possible a minimal demo of the problem:
When I start OpenOffice, I get the following message:

Document Server version:
9.0.4

Type of installation of the Document Server (docker, deb/rpm, exe, please point us to the installation guide that you used as well):
Docker

Connector version:
9.0.4.50

DMS (platform) version:
Linux from LinuxServers Docker.

OS:
Unraid

Browser version:
OperaGX 121.0.5600.47/Safari

Additional information:
It seems to me that most of the time everything worked fine when I added individual files. OpenOffice is on DNS via Cloudflare.

Any relevant details about the situation. If you’ve modified configuration files or are using a proxy server that might affect the situation, please mention it. You can also attach images and videofile to the post (or to place them to external storage).

I use CloudFlare and Nginx.

Hello @Kulis

First of all, note that you are referencing here version of Document Server:

Please find version of the connector app in Nextcloud > Apps > Installed or Active. Please specify version of Nextcloud too.

Also, please let me know if:

both Document Server and Nextcloud are mutually accessible to each other (simple wget to each resource should do the trick);
Document Servers’ integrated test example works (go to Document Servers’ address to find instruction on how to activate it and GO TO TEST EXAMPLE button;
Document Server and Nextcloud are installed on the same server or different ones;
if any service (CloudFare or Nginx) are configured as proxy.
