If you are having trouble configuring WebDAV here are some tips:
A self signed certificate won’t work. Services such as letsencrypt.org provide free certificates which are recognized by iOS.
Make sure the time on your iOS device and the server are both correct.
Check the permissions of the files on your server - make sure that beorg will be able to update them. If you find that changes made in beorg aren’t reflected on the server this might be the issue.
You can get detailed debug information on WebDAV problems using the beorg REPL - see below.
Using the beorg REPL to get more information on your issue:
Tap the Settings tab in beorg
Tap the REPL button (top right)
Type, including the parenthesis, (log-contents)
Look in the text output by this command for where the beorg sync happens. It will give you any error codes from your server and tell you which files beorg thinks it needs to upload or download
Please note that whilst we will try and help you out with any WebDAV configuration issues they can be complex and there is a limit to how much help individual users can be provided - particularly if running their own servers.
