PH Cloud CalDAV Sync

Does not sync with Zimbra (carddav & caldav URLs), tried to connect, non-SSL, straight through on port 80, so unencrypted, does not work either. Error: The text associated with this error code could not be found. Well, if the app can't find the error, do you expect we dig through the code to find it? Not useful at all.

Fails to connect to Fastmail's caldav server, possibly because Fastmail requires SSL and this app doesn't have an option for that. Doesn't provide any useful error reporting.

Sadly this doesn't work with owncloud.

There's no option to select SSL, so this will not work.

can't connect to radicale dumb server. radicale uses port 5232, i don't know if this is the problem because the error message says "Error: the text associated with this error could not be found". pretty much worthless.
