The Basics

Nextcloud Server version (e.g., 29.x.x):
- 33.0.3
Operating system and version (e.g., Ubuntu 24.04):
- ubuntu 24.04
Web server and version (e.g, Apache 2.4.25):
- NGinx

- NGinx
PHP version (e.g, 8.3):
- 8.4.21
Is this the first time you’ve seen this error? (Yes / No):
- yes
When did this problem seem to first start?
- after pulling documentserver(latest)
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- docker
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- no

Summary of the issue you are facing:

I have a script that is updating my ONLYOFFICE (docker) with the latest (stable)

two times per month. The latest version i s 9.4.0.1

I can reach my ONLYOFFICE by url OO-FQDN:443 or NC-FQDN:8443 without issues.
The “connector” (ONLYOFFICE App is 10.0.0 from the nextcloud app store) and a self test says connection established (green tag)

When opening documents i get a blank page (word) or a blank table (calc)

With new docs the same.

My ONLYOFFICE docker container resides on the nextcloud server (192.168.55.16)

Steps to replicate it (hint: details matter!):

update docker image for onlyoffice documentserver from 9.3.x to latest(9.4.x)
downgrade to a lower version e.g. with docker pull onlyoffice/documentserver:9.3.1.2
restart docker and container, restart nginx (php), reconnect to nextcloud and see that docs can be edited as expected!
seems that ONLYOFFICE App can no longer make onlyoffice/documentserver docker accessible within nextcloud? Can anyone confirm?

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

The script that is pulling my ONLYOFFICE docker image is

#!/bin/bash
#
docker stop ONLYOFFICE
docker rm ONLYOFFICE
docker image rm $(docker image ls | grep onlyoffice/documentserver | awk '{ print $3 }')
docker system prune -a -f
#
docker pull onlyoffice/documentserver:9.3.1.2
#
cat /etc/letsencrypt/rsa-certs/privkey.pem > /app/onlyoffice/DocumentServer/data/certs/onlyoffice.key
cat /etc/letsencrypt/rsa-certs/fullchain.pem > /app/onlyoffice/DocumentServer/data/certs/onlyoffice.crt
echo "Starte neuen Container ONLYOFFICE; Portmapping 8443:443"
#
docker run --name=ONLYOFFICE -i -t -d -p 8443:443 --restart=always --add-host=NC_FQDN:192.168.55.16 \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql \
    -e JWT_ENABLED='true' -e JWT_SECRET='MY_SECRET' onlyoffice/documentserver:9.3.1.2
#
# restart services
systemctl restart php8.4-fpm && systemctl restart nginx && systemctl restart postgresql
exit 0

usually i am pulling pull onlyoffice/documentserver (for latest) but for now i switched to a fixed version (9.3.1.2)

Tips for increasing the likelihood of a response

Use the preformatted text formatting option in the editor for all log entries and configuration output.
If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

Since update onlyoffice/documentserver to 9.4.0.1 (latest) dcuments don't open in nextcloud (33.0.3)

offen 11:51AM - 20 May 26 UTC

chrissi55

I use nextcloud on ubuntu 24.04. (no docker AiO) NC version is 33.0.3; ONLYOFFIC…E app is 10.0.0 I pulled my documentserver with ``` docker pull onlyoffice/documentserver # docker run --name=ONLYOFFICE -i -t -d -p 8443:443 --restart=always --add-host=MY-NEXTCLOUD:LOCAL_IP \ -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data \ -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice \ -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \ -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql \ -e JWT_ENABLED='true' -e JWT_SECRET='MY-SECRET' onlyoffice/documentserver ``` Testing https://MY-ONLYOFFICE-URL:443 => success see that ONLYOFFICE is working Testing https://MY-NEXTCLOUD-URL:8443 => success as well Editing / Opening existing *docx *xlsx etc. files delivers blank pages. New documents the same. I have cleared browser cache, maintenance:repair in nextcloud -> no effect from the logs docker logs -f ONLYOFFICE i see the following ``` ==> /var/log/onlyoffice/documentserver/nginx.error.log <== 2026/05/20 11:01:09 [error] 11215#11215: *34 open() “/var/www/onlyoffice/documentserver/web-apps/vendor/socketio/socket.io.min.js.map” failed (2: No such file or directory), client: REVERSE-PROXY-IP, server: , request: “GET /9.4.0-ff369681c3b817a16611f2fa73d6b42a/web-apps/vendor/socketio/socket.io.min.js.map HTTP/1.0”, host: “OO-FQDN” 2026/05/20 11:01:09 [error] 11215#11215: *33 open() “/var/www/onlyoffice/documentserver/web-apps/vendor/underscore/underscore-umd.js.map” failed (2: No such file or directory), client: REVERSE-PROXY-IP, server: , request: “GET /9.4.0-ff369681c3b817a16611f2fa73d6b42a/web-apps/vendor/underscore/underscore-umd.js.map HTTP/1.0”, host: “OO-FQDN” ``` With documentserver version 9.3.1.2 everything works fine if i "downgrade" and pull the older ONLYOFFICE docker image from dockerhub. My reverse proxy conf file for ONLYOFFICE is the following ``` server { listen 443 ssl; # see: https://codefaq.org/server/how-to-address-the-deprecation-of-the-listen-http2-directive-in-nginx/ http2 on; server_name OO-FQDN; # SSL Config for all redirected Target URLs ssl_certificate /etc/letsencrypt/ecc-cert/fullchain.pem; ssl_certificate_key /etc/letsencrypt/ecc-cert/privkey.pem; ssl_trusted_certificate /etc/letsencrypt/ecc-cert/chain.pem; ssl_dhparam /etc/nginx/ssl/dhparam.pem; ssl_session_timeout 1d; ssl_session_cache shared:SSL:50m; ssl_session_tickets off; ssl_protocols TLSv1.2 TLSv1.3; # Framing-Prevention - do not use this URL for Phishing / Framing ssl_ciphers 'TLS-CHACHA20-POLY1305-SHA256:TLS-AES-256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384'; ssl_ecdh_curve X448:secp521r1:secp384r1:prime256v1; ssl_prefer_server_ciphers on; set $upstream LOCAL-IP-NEXTCLOUD_ONLYOFFICE; # # Configuration for OnlyOffice # location / { proxy_pass https://$upstream:8443; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Upgrade $http_upgrade; } } ``` The docker is running on the same server than nextcloud - the REVERSE-PROXY and NEXTCLOUD / ONLYOFFICE have different LOCAL-IPs I can't figure out what exactly the problem is. I can reproduce the error by switching between documentserver versions 9.3.xx and 9.4.xx I don't know exactly if we need a new ONLYOFFICE app update in the nextcloud app store to make nextcloud "talking" to ONLYOFFICE server again. Thanks for any help!

Brave fails to load onlyoffice documents - it's blocking Analytics.js

opened 07:43PM - 19 May 26 UTC

confirmed-bug

### This issue is unique. - [x] I have used the [search tool](https://github.co…m/ONLYOFFICE/DocumentServer/issues?q=) and did not find an issue describing my bug. ### Operating System of DocumentServer Docker ### Version information Version: 9.4.0. Build: 129 ### Expected Behavior Have onlyoffice running in docker integrated with nextcloud. Has worked flawlessly for months until i updated the docker image to the version noted avove. I consume it from the brave browser that is at version: 190.122 ### Actual Behavior After the upgrade to the version stated avobe the onlyoffice web page only loads partially, I see the spaces where the toolbars should appear and the space where the document should load but none of them completes the drawing. Using devtools i see that brave is blocking the load of the file Analytics.js This is because the file name triggers the Brave filters for undesirable content. ### Reproduction Steps Update to the version of onlyoffice in docker estated above. Access the web site with brave trying to open any document (have tried only documents, not spreadsheets). ### Additional information Neither Edge nor Chrome are afected but for Brave it fails for all documents. I guess that changint the name of the file to something different could be a suitable solution. In the meanwhile i have added an exception to brave as a bypass...but this of course will be rather undesirable or even unfeasible for most brave users
