How to connect to Evernote through a firewall or proxy server

First, make sure you're running the latest version of Evernote. When Evernote attempts to connect to the Internet for syncing purposes, it uses the operating system's default browser Internet settings. Evernote utilizes TCP ports 80 and 443 for connection to Evernote's web service, so both of these ports need to be accessible by the Evernote application.

The easiest way to check that these settings are configured properly is to visit the following two URLs using Safari on Mac OS X or Internet Explorer on Windows:

If you're unable to access either of the URLs above in your web browser, it's unlikely the Evernote desktop application will be able to sync successfully.

If you're unable to sync at your office, it's possible that your employer's IT security policy is disallowing access to services like Evernote. If you're unsure, contact your company's IT department for clarification.

If you're able to access the above URLs and you're not attempting to access Evernote from inside an office (or similar) network, please contact us. It's helpful to include the following in your ticket submission:

  • A copy of your activity log
  • A description of what is happening
  • What version of Evernote you are using
  • A list of all the steps you took before you contacted Evernote Support


  • internet connection
  • connect
  • connection
  • sync error
