Using nextcloud 17.0.2 and documentserver:5.4.2.46 docker images on same server. Both services are working but opening a file in browser displays "The document could not be saved" error message.
Error message points to this url https://api.onlyoffice.com/editors/troubleshooting explaining that the callback handler is not working. "The document editing service cannot connect to the document storage service at the editorConfig.callbackUrl address."
Unsure how to set the callbackUrl any help would be greatly appreciated.

Server address for internal requests from the Document Editing" defaulted to http://nc.example.com which is wrong, https://nc.example.com is correct. Also must us FQDN not docker service name.
