Document could not be saved error - nodeJS - postData error: url


I have installed docker and have followed this guide to install onlyoffice: Installing ONLYOFFICE Docs for Docker on a local server - ONLYOFFICE

Document Server version: Version: 8.0.1-31
Type of installation of the Document Server docker
OS: Ubuntu 20.04
Browser version: Mozilla Firefox 125.0.2

I have an external IP 155.34.x.22 which I use for this onlyoffice server forwarding port 8443. I could access to onlyoffice server page with but editor page keeps loading and shows this error:

[2024-05-17T11:32:56.616] [ERROR] [localhost] [103.76.x.120new.docx1715937556917] [uid-1] nodeJS - postData error: url =;data = {“key”:“103.76.x.120new.docx1715937556917”,“status”:1,“users”:[“uid-1”],“actions”:[{“type”:1,“userid”:“uid-1”}],“token”:“xxxxxxxxxxx”} Error: connect ETIMEDOUT 155.34.x.22:8443
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1187:16)

If I use wget, it could resolve public IP and it stuck in connecting.

Appreciate of your assistance here.



I have resolved the issue. I figured out dockerserver is trying to reach to public address and my internal firewall was blocking this. After allowing to access to public address from inside, it is working now.


We are glad to know that the issue’s been resolved
