Nextcloud / OnlyOffice Refused To Connect

After configuring the ONLYOFFICE connector for Nextcloud and saving the Server settings, the Common settings, Editor customization settings, Common templates, and Secure view settings sections do not appear.

Hello @ckvtz
Please reproduce the issue and record a video file. After that please collect 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

A few more things. Please specify Document server version and check out mutual availability between servers with wget\curl commands (go to Nextcloud and run wget https://DS_domain_name; and vice versa, from DS server run wget https://NC_domain_name).
