My DEVONthink Pro Office (Version 2.3.3 on a Mac Pro) is not detected by the DEVONthink to Go App on the iPad (iOS 5), if i try to sync. some Documents. No Device is listed, when i start the Sync. Function on the iPad and after a while, the error message “Bonjour failed” occurs.
Restarted all devices, reinstalled DTTG many times on the iPad.
Do you use a firewall on the Mac Pro? That can sometimes interfere with the sync process.
I’m assuming you have the Mac Pro hooked up to a router with an Ethernet cable? I’ve read that some routers put wired connections on a different sub-network than wireless connections, which can also interfere with Bonjour. If you compare the IP address of the Mac Pro with the IP address of the iPad, the first three sets of numbers should be the same. If they’re not, they’re probably on a different sub-network. If that’s the case, there should be a setting on the router to change this behavior, but we’d have to know the router model to figure it out.
Have you successfully synced DEVONthink To Go before or is this your first time?
Another thing you can try is to download Bonjour Browser and use it to confirm the Sync Agent is correctly hosting its Bonjour service for DEVONthink Pro Office. When you launch Bonjour Browser, you should see a list of Bonjour services on your Mac Pro, including one for DEVONthink.
What type of router do you have? There could be another setting that’s interfering with Bonjour.
Is it possible your iPad is on a different network? E.g., over here I have my private wireless network, and another one for guests. Or it could be a neighbor’s network. Sometimes the iPad camps onto the wrong network and DTTG won’t find DEVONthink desktop.
Do you have UPnP enabled? If not, try enabling it and trying again. There should be an Advanced Network page in the web interface of your router which has this option (also page 40 in the manual I linked to).
I had the same problem and solved it by simply connecting my iPhone with DevonThink To Go to my MacBook Pro with Devonthink Pro Office via the USB cable that comes with the iPhone. The device was then recognized and I could synch the apps. For some reason, Bonjour could not recognize the MacBook even though it showed up in the Devonthink To Go’s window on my iPhone. Anyway, forget the wifi sync and just use your connector (at least for now). If anyone does know of a wifi sync solution, please post it here. Thanks.
