Syncing error "(os error 10060)" in office (Windows 11 Proxy problem)

Hi folks,

I’m getting this error when launching Anki on my Windows 11 work laptop:

A network error occurred.

Error details: error sending request for url (): error trying to connect: tcp connect error:

(os error 10060)

Screenshot 2023-07-15 152947

Anki Version ⁨2.1.65 (aa9a734f)⁩ with Qt 6.4.3.

When I work remotely using my home’s Wifi, I use a pre-configured corporate VPN client and have no issues launching Anki and syncing with my progress, but when I work in-person, at my desk in the office, and connect my laptop to the office Intranet via Ethernet cable I am unable to connect to ankiweb and sync my progress.

I have tried adding anki to the list of apps allowed on the Windows Firewall then rebooted the machine but this problem persists.
I feel strongly this must be something on the Proxy config, can anyone guide me through the Windows 11 Proxy server exception?

My company has a configuration script for the proxy installed on every workstation. Every other setting is disabled or not active in Windows’s Proxy settings.


  1. just checked both firewalls (Windows’ domain FW and Panda’s) as suggested in the Anki manual “Error establishing a secure connection.” when syncing" chapter – both seem disabled yet error 10060 persists. Any other suggestion?
  2. Also tried the work around explained in ‘Syncing failed: Connection timed out’ errors when syncing chapter of the Anki manual, ie connecting via office Wifi rather than the Ethernet cable – still getting error 10060. :frowning:
  3. the ‘mtr’ tool’s link is dead, any alternative application to detect packet loss on Windows? [WinMTR download |]
