Publish OnlyOffice WorkSpace behind a "Nginx Proxy Manager" reverse proxy

Hello to the Only office community.
I allow myself to come to you for help.
I installed OnlyOffice Workspace without a certificate (http://Ip server onlyoffice) using Docker on my local network.
I want to publish my OnlyOffice Workspace server on the internet in http.
For this I used the reverse proxy (Nginx Proxy Manager).
However I find myself faced with a problem, OnlyOffice Workspace works correctly with the exception of Webdav.
Webdav does not work whether I am on my local network or on the internet.
I need to keep the reverse proxy (Nginx Proxy Manager), I have other services that use port 443 with Let’s Encrypt.
Can you help me solve this problem please?

Hello @angel974

Sorry for the late reply.

It is quite hard to understand with your description why WebDAV does not work.
Could you please provide any screenshots from the portal interface that are related to the issue? Also, please while reproducing the issue check out browsers console for any errors entries too and share with us.
