Sync seems to be stuck on `not yet synchronized, upload database`

hi all and @BLUEFROG

i decided today to restart my Devonthink sync since i have been getting real inconsistent sync lately on my iOS devices.

so started from scratch, cleaned/removed all previous sync locations. then added a CloudKit sync option but am seeing this for past 8h

dosent seem its going anywhere (and my Databases are small)

any clue on how to deal with this?



As a test, turn off CloudKit and rely on Bonjour for sync (which it looks like you have setup). Test if that works. If it works, then likely the issue is Apple’s CloudKit (maybe).

thx @rmschne, the bonjour was accidentally marked, I’ve never use it :slight_smile:

disabling it didn’t help either :slight_smile:

thx again


That is a pity as it is much more reliable and vey much faster than any sync using a third party sync server.

hmm @rmschne , im very open to try it then :smiley:

will that work on any iOS device? ill go ahead and do some reading on this



Read the instructions in the DEVONthink Handbook (or in Help).

To answer your specific question won’t work on any device–there are minimum specs and DEVONthink ToGo version requirements. See the Handbook.

I call my iMac the one device that accepts incoming. I sync via Bonjour, WebDav to a NAS on the local network, and to Dropbox (and to CloudKit for one small database just to prove it works) with a MacBook, iPhone, and iPad.

Just don’t overload the IOS devices. They aren’t computers in the same league as Macs.

ok so had a bit of a reading of the help file as suggested and setup bonjour

so do i understand correctly that for me to sync the mac to the iPad i need to also alongside this use Webdav to do the actual syncing or am i way off?

sorry for being very non technical :slight_smile:



“Way off”. What did you read to give you that impression? Please quote the page number on the Hanbook.

Also, before you get all into synching … best to make sure you actually need it.

thx again @rmschne :slight_smile:

well yes i want to have my food and tech Databases available with me on all my iOS devices so there is a need :slight_smile:

as of where i got it, well i enabled bonjour on the mac and then on the iPad (not checking allow incoming connections) yet nothing really happened. i assumed i need to do something to define which databases to sync and how to do so but this is where i got lost :smiley:

as you can see on the mac i can see the iPad yet i dont get an option other then inbox to choose what to sync


A correct setup on Mac for Bonjour does not show to you the other devices. I do not know for sure what you have done, and since I don’t know for sure I’m not going to speculate. The best instructions (better than I can or will re-state here) for how to setup Bonjour are in the Handbook, which I suggest you re-read and follow exactly.

Clue: configure access on the iOS devices TO the Mac that accepts incoming.

Final advice: do not overload the iOS device with a huge amount of data that just causes you to say “it takes a long time” as lots of data will indeed fill up the device and take a long time. Your mileage may vary, of course.

thx again

after reading this post

things finally made sense (sorry for me the handbook wasn’t as clear as that post…maybe its just me…)

anyway after i setup everything im getting the mentioned:

General CFsocket error / AsyncSocketErrorDomain 2


i don’t have the firewall activated on the mac (the Devonthink server) and rebooted all macs, iPads and iPhones but still cant connect

would really appreciate any help to debug this…



Relied on a Post and it didn’t work. Humm…

I quote from page 61 of the DEVONthink Pro 3.6.3 Handbook these clear and simple instructions without edits. No post anywhere is more clear or simpler.

Bonjour Setup:

Step 1: On the machine acting as the server, open Preferences > Sync and press the Bonjour Options button.
Step 2: Click Enable Incoming Connections to use this Mac as a Bonjour server of
its databases. Optionally, have closed databases open when a client initiates a sync.
Step 3: Enter a mandatory password. This password is required for other devices to act as a client of DEVONthink’s. If you are working with an IT department who has assigned a port for you, or you have a port you’d specifically like to use, enter it in the Port field. Otherwise, leave this blank and DEVONthink will assign one for you.

The Mac with Bonjour enabled should now be visible as a sync location to other devices on your local network. On the other devices, enable it, enter the password, and you can import databases or sync existing databases directly with it.

Note: You should never use more than one device as a Bonjour server for a given database.

  1. The first place you should always look when having a potential sync issue is Window > Log.
  2. Bonjour is not only covered in the Help referred to by @rmschne, but I did a more exhaustive dive here:

thx @BLUEFROG , as always your help is top notch

first of all your link and your simple instructions were IMHO much more clear then the help file (at least for idiots like me… :slight_smile: i highly suggest you move that to the help section…just my 2 cents…)

back to the point. i did follow all your instructions on the mac and the iPad up until the point of the

Set the options per your choice and touch Save.

then i get this error

i am using latest big sur and latest iOS (14.5), latest Devonthink , have no firewalls one mac or router, and all devices are on the same LAN and seem to see each other on the network

any clue how to resolve this?

kind regards


Fyi @BLUEFROG author of both.

That is a transient error.

Try quitting and relaunching DEVONthink and DEVONthink To Go.
You may also consider rebooting the Mac - not just because it’s good to do occasionally (weekly is nice), but in case a port was stalled.

I’ve considered it. However, I have to consider large scale restructuring and it’s affect on the PDF, .MOBI, and .EPUB as well.
So far, the succinct presentation in the Sync section seems to be successful so far. :slight_smile:


i did reboot both the Mac and iPad but the same error still appears

i currently cant get either bonjour or CloudKit to work so cant sync…would appreciate any other ideas on how to try and debug bonjour

thx again


You didn’t respond to this earlier.

sorry about that

the current log window seems to have nothing

would be very happy to provide any other missing information
