Hello @vdkns
Please provide us with additional details. If it’s possible please reproduce the situation (step-by-step usage scenario) and record a video file.
Additionally, please provide us with whole document server logs folder. It’s located here:
docker: /app/onlyoffice/DocumentServer/logs/documentserver/
deb\rpm: /var/log/onlyoffice/documentserver/
Windows: Program Files\ONLYOFFICE\DocumentServer\log

Thank you for provided data.
Do you have any proxy-server in front of Document server?
Also, please reproduce the situation (with correct Document server address on the connector page) and send us whole Document server folder.
Additionally, please let us know how exactly you installed the connector app.

  1. Do you have any proxy-server in front of Document server? - no (Document server and odoo in the same local network, both virtual servers on hyper-v server 2019, access from internet by NAT)
  2. Also, please reproduce the situation … - all files in google drive
  3. Connector installation process:
  • downloaded from ONLYOFFICE | Odoo Apps Store
  • unpacked in /usr/lib/python3/dist-packages/odoo/addons/onlyoffice_odoo (as root user)
  • activated developer mode in odoo (Settings - Activate the developer mode)
  • updated Apps list (Settings-Update Apps List)
  • in search field removed filter Apps and typed “onlyoffice”
  • activated connector (connector`s icon did not show, after rebooting server appeared)
  • server rebooted (sudo reboot)

P. S.
Regardless the data in connector settings (correct Document server address or blank page or random address or any security data) - error the same

Thank you for provided data!
Could you please check out mutual availability between servers? You can do it with wget\curl commands, for example, go to Document server and run wget https://Odoo_domain_name. And vice versa, from Odoo server run wget https://DS_domain_name.
One more thing, is it possible to update Document server to the latest version (v.7.4) and double check the situation?

  1. mutual connections between servers is ok

  2. document server updated to v

  3. still error

Hello @vdkns

I’d like to participate in this thread too.
I just noticed that the steps you’ve performed to manually install the connector app differ a bit from the documentation. Please refer to this articles’ installation section and try installing the connector app according to the Option 2 (manual installation):

Let me know the result afterwards.

  1. i checked all installation steps (according to manual installation instruction), of course the package pyjwt was installed (i forget mention about it )

  2. and make experiment

  • remove connector, delete connector folder from /usr/lib/python3/dist-packages/odoo/addons/onlyoffice_odoo and reboot server
  • add in odoo.conf addons_path = /mnt/extra-addons
  • put connector in /mnt/extra-addons
  • switch Odoo to the developer mode and click Apps → Update Apps List …
  • welcome the same error

There is an issue currently in the connector plugin:

As you can see the issue was fixed but the new version of connector plugin is not released yet. However, commit is already available and can be used.
You need to change the code according to the commit lines in the config and then restart Odoo. was changed, but error remain

We have just released new version of the connector plugin for Odoo:
Please remove your currently used one and try again with new one. Let me know the result.

  1. Nothing changed (except lines numbers in traceback)
  2. The module ONLYOFFICE Documents cannot be installed, because depends from module “documents”

As it comes from the screenshot with dependency, you need to have both ‘onlyoffice_oddo_documents’ and ‘onlyoffice_odoo’ modules installed. Make sure that they are installed on your server and are up to date.

“As it comes from the screenshot with dependency, you need to have both ‘onlyoffice_oddo_documents’ and ‘onlyoffice_odoo’ modules installed …” - it`s impossible! Because ‘onlyoffice_oddo_documents’ depends from module ‘documents’, and cannot installed without it. Where can i get module ‘documents’ !?

On this screen you have both plugins for Document Server to integrate it. However, Documents module from Odoo itself is missing. It is stated on the integration page that:

This app enables users to edit and collaborate on office documents within Odoo Documents using ONLYOFFICE Docs.

Basically, Document Server requires Documents module from Odoo and plugins for the integration for proper integration.

No Documents module in odoo 16 community edition :frowning:

For Community Edition of Odoo you need only one plugin to integrate Document Server:
Get this one, remove another one and restart Odoo, then try connecting again.

Rest of those are required for Enterprise Edition. I am sorry for missing that point.
