For first post, please answer the questions below! ### Describe your issue in detail cannot get collabora to work. getting blank page and browser console says 502. I dont need ssl or reverse proxy. i just want to access via plain http and custom ports provided. `http://filesuite.domain.local:8080/browser/dist/cool.html?host=ws://filesuite.domain.local:8080&WOPISrc=http%3A%2F%2Ffilesuite.domain.local%3A8080%2Fwopi%2Ffiles%2F8914ab50-3576-4a3e-8ee1-1b82aca9883e&access_token=C4lrcBWse_R7U1vnVqeOyfDWtuTs5s5hXz6a2hoild8.avFCqFFgqiEDJFG3heZAnzXU-GyfDMGgJkzYN6VRorI&permission=edit&lang=de 502 (Bad Gateway)` ### What version of Cells are you using? latest ### What is the server OS? Database name/version? Browser name or mobile device description (if issue appears client-side)? Debian 12 ### What steps have you taken to resolve this issue already? Already searched the entire forum and tried to apply all fixes ive found but its still not working trying for 6 hours now This is my docker-compose file: version: “3.9” services: mysql: image: mysql:8 restart: unless-stopped command: - --character-set-server=utf8mb4 - --collation-server=utf8mb4\_unicode\_ci environment: MYSQL\_ROOT\_PASSWORD: “${MYSQL\_ROOT\_PW}” MYSQL\_DATABASE: cells MYSQL\_USER: pydio MYSQL\_PASSWORD: “${MYSQL\_PYDIO\_PW}” volumes: - mysql:/var/lib/mysql cells: image: pydio/cells:latest restart: unless-stopped depends\_on: - mysql ports: - “8080:8080” environment: CELLS\_BIND: “0.0.0.0:8080” CELLS\_EXTERNAL: “http://${FQDN}” CELLS\_NO\_TLS: “1” CELLS\_LOG: production volumes: - cells:/var/cells - data:/var/cells/data collabora: image: collabora/code:latest restart: unless-stopped hostname: collabora depends\_on: - cells ports: - “9980:9980” cap\_add: - MKNOD environment: DOMAIN: | filesuite.domain.local(:8080)?|collabora EXTRA\_PARAMS: “–o:ssl.enable=false” volumes: mysql: cells: data: collabora: Settings in Collabora Plugin section: ![image](https://canada1.discourse-cdn.com/flex032/uploads/pydio/original/2X/9/9668045c168e0d6eb2fbcf57069a6636e35b9ae2.png) would be very grateful for support ---

Hi and welcome to the forum. I have this in a recent setup that works smoothly: ```auto # in docker compose file office: image: collabora/code:latest restart: always expose: ["9980"] cap_add: - MKNOD environment: - aliasgroup1=https://${ESCAPED_FQDN} - domain=${ESCAPED_FQDN} # where ESCAPED_FQDN=files\.example\.com => the "\" before the dots are important or it won't work # in the pydio.json (or the plugin editor in admin web ui) "editor.libreoffice": { "LIBREOFFICE_CODE_VERSION": "v21", "LIBREOFFICE_HOST": "office", "LIBREOFFICE_PORT": 9980, "LIBREOFFICE_SSL": true, "LIBREOFFICE_SSL_SKIP_VERIFY": true, "PYDIO_PLUGIN_ENABLED": true }, ``` ---

Have you been able to get it working? Can you hit it by IP alone and without using the FQDN? I believe there are errors in your collabora yml syntax. ---

Hi, When you use ‘filesuite.domain.local’ as domain, collabora docker will try to connect to wopi service via ‘[http://filesuite.domain.local](http://filesuite.domain.local)’ So, make sure that your docker collabora understand this fqdn. To troubleshoot, you can go to collabora container then ping to this fqdn ---

For the record, I had some issues configuring the docker compose setup with collabora and I found some very interresting hints in NextCloud forum 😳 It is worth having a look to understand what is at stake and better configure your specific setup: > **[Collabora integration guide](https://help.nextcloud.com/t/collabora-integration-guide/151879)** > > Collabora integration guide Nextcloud integrates functionality to edit office documents online (even collaborative - meaning multiple users can work on the same document at the same time). This integration primarily happens with Collabora Online,... ---

thank you for your help so far. ive managed to get it started. but when i open a document it just shows up as a blank white page. The error message in pydio docker log is `Error in libreoffice reverse proxy: context canceled {"error": "context canceled"}` ---

Hi, I have reworked on my setup today and it appears the config I gave above had a few issues. I have corrected it with the setup that I am using now without issue. Could you please try to adapt yours like this and see if it works? For the record, to troubleshoot, you should: - Ensure that both `cells` and `office` docker images are up and running (and in the same docker network) - Log in the running **cells** docker image and verify that you can ping the collabora container with this command: `ping office` - Try to open this page: `https:///hosting/discovery`: you should see an xml `` tag ---
