brother printer/scanner cannot upload scanned document
it was working yesterday, now I have 2 Brother printers/scanner, different model that I try to scan and upload the scan on dropbox and it fail. Does dropbox have server down or any upgrades happen in...
I resolved this issue with my Brother MFC-L3710CW unit by logging into the machine and changing the TLS setting to 1.1/1.2. (192.168.... in web browser). It works with Dropbox Brother app now. It's always work for the MS OneDrive Brother app. You will need your units password to login to the administrator side of the Brother unit. Find it on the rear of the unit by the power cord input. Hope this helps!
Hi @Walter,
Situation is actually the same as @borea_usinece described a year ago.
Suddenly, scan to web into Dropbox didn't work anymore. Connection Error 03 on the display as soon as the scan usually is uploaded to Dropbox. Multiple MFC printers in different networks have the same issue. No network or printer setting was changed.
On one device I created a new Dropbox connection resulted in the same error at the end.
I'm having the exact same issue. Discovered it first last night, an hour or so before @hemzet wrote his last message here. Connection Error 03 saving to Dropbox, no settings changed. Using a Brother DCP-9020CDW. Internet says it's because of proxy settings, but all other features works just fine, including printing via wifi.
