Just to consolidate, here are the errors and info I’ve received in the logs:

- Request failed with http status code 503 - CKErrorDomain6
- Zone does not exist - CKErrorDomain26
- This operation has been rate limited due to an earlier error: Request failed with http status code 503 - CKErrorDomain7

It works for me on Mac when I set max connections to 4.  
Also it fails when I start sync on my 2 devices (but when I close app on iOS, Mac DT start syncing again) .

2 TB, with 1.5TB of free space.

Btw, on a positive note… the sync via Cloudkit appears to be much faster, very much appreciated 🙂

The transfer of my 15.1 Gb database just finished. No changes from the default settings. Just had to wait through the rate limit / burst of data cycle until it finished.

Just tried a really small database, my global inbox, with 37 items, 21 Mb. It uploaded immediately, no errors.

Among all those recurring log messages, there’s a new one in between. Don’t know if this helps or is related to this issue, but maybe is useful:

FWIW: I’ve uploaded 5 more databases (all \< 2 GB) without errors. I have two larger databases left to upload. By watching the DTPO status line and error log, it looks to my eye that the CKErrorDomain 6 errors appear for large files in a database, whereas the CKErrorDomain 7 errors occur appear for large NUMBERs of files. Both have been temporary for me needing no corrective action aside from waiting for DTPO to retry and complete the upload.

I have a total of 6 databases. The first one, which is 4.64 GB uploaded without issue. The second two I’m trying to upload are both under 2 GB and both keep getting the errors. (I am attempting one at a time.)

For me similarly, biggest problems were with databases that contained many pdfs, but finally synced on my mac! now I need sync my other iOS devices 😛

I just finished a support ticket and the 6 and 7 errors occurred within a finite time span. After about half an hour the sync quickly finished as the engine resumed its attempts.

</div>

Sync just stops on mine after a while and doesn’t attempt to finish. If I kill DEVONthink, it will start synching again, but then hangs. It’s synching, but there are a lot of gyrations to make it go. After the last restart (about 5 minutes ago), I am at least getting the same errors in the logs letting me know it is at least trying.

Sync doesn’t constantly retry. It should resume on its own within 4-5 minutes. Don’t just kill it. Be patient with it.

It seems my databases have finally completed uploading. It took over 5 hours to upload 6 databases totaling 17.76 GB. My iMac’s hardwired upload / download speeds are currently 859/720. Going to attempt uploading to my iPad.

</div>

Mine stopped again. There has been no attempt by DEVONthink to sync for 1 hour and 7 minutes. When I go into the sync tab in properties, all options are greyed out, with the exception of **Refresh List**. Clicking **Refresh List** causes the spinning circle to appear over the icon of the **iCloud (CloudKit)** location, but no other operation takes place. At 1 ½ hours after the last activity I will restart DEVONthink again and see what it does.
