Hello, and thank you in advance. A link to the answer will suffice.

I am trying to synchronize DT with iCloud (both of them), but I keep getting a key error.

I have already changed the key three times, on my Mac and iPhone, but nothing works.

I have already deleted directories 3/4 and re-entered a key, but it’s still not working.

On DTTG, I have already deleted the app twice and I am still getting the same key error.

So I have clearly missed something, but I’m stuck and would appreciate your help.

Resintalling software rarely fixes most issues. Sometimes a full re-start fixes things, though.

I suspect Apple iCloud is failing you. Some find it an unreliable service. From reports I’ve read iCloud services work well some places on the planet and not so well in others.

Do you need internet syncing? if your Mac and iPhone are on the same local network, can you use Bonjour? It’s more reliable and quicker than any internet syncing.

Hello and thank you for your feedback.

I had already had problems with iCloud,

it had worked and then I discovered that synchronization with the database had failed (on both iOS and OS X). I think the change of iPhone may be behind this.

I just looked at Bonjour (it seems to have a lot of settings)😕

In any case, thank you very much for these interesting leads.

Correct. You can’t just change the keys and expect it to somehow work. his

Delete what _“directories 3/4”_

Since you’ve changed lots of settings and we’re not sure what the error was or how you might have made it worse, I personally would be a big fan of deleting any current sync store, disabling all sync, and starting from scratch while following the manual. That should fix whatever issue you’re having!

Thank you for your various responses.

After reading the manual, I deleted all iCloud destinations.

I then restarted without entering a password (by mistake), but everything works…

I will try to set a password later 🙂

Thank you very much and have a great weekend, everyone.

I hope you noted in the documentation, this cannot be done retroactively. You will need to clean the sync data, modify the key’s value, then resync the desired databases again.
