Code42 Support

End of support for port 4282 in the Code42 cloud

Announcement date October 3, 2019

Overview

To continue to improve and ensure the security and integrity of the Code42 cloud, Code42 will implement a networking change effective February 4th, 2020 that will:

  • Remove the ability of Code42 apps to use port 4282 to communicate with Code42 cloud destinations.
  • Result in Code42 apps older than version 5.4 (with the exception of versions 4.8 and 4.9) being unable to connect to Code42 cloud destinations.

Affects

This change affects all Code42 customers (both Code42 for Enterprise and CrashPlan for Small Business) who:

  • Run unsupported Code42 apps older than version 5.4 with the exception of versions 4.8 and 4.9, and
  • Use Code42 cloud destinations for storage.

This change does not affect Code42 customers who:

  • Run supported Code42 app versions on port 443 and/or 4287, or
  • Have on-premises installations of Code42 that use on-premises storage.

For supported app versions, see the Code42 version policy

Frequently asked questions

How can I ensure uninterrupted service?
  • Ensure ports 443 and/or 4287 are open for Code42 app communication, and
  • Run supported versions of the Code42 app. 

To continue to connect to Code42 cloud destinations, you may still run unsupported Code42 app versions 4.8, 4.9, or 5.4 and later. However, we strongly recommend you upgrade to supported versions of the Code42 app to ensure the latest functionality and security updates. We cannot guarantee the stability or reliability of unsupported versions.

What happens if I don't do the preceding tasks?

Any Code42 apps attempting to connect to Code42 cloud destinations using port 4282 will be unable to connect. 

How do I find the devices currently running unsupported Code42 app versions?

Code42 for Enterprise customers can run the device status report to find devices running unsupported versions of the Code42 app. 

How do I know if my Code42 apps will connect after February 4, 2020?

Review our Test your network connection article to verify connectivity of your Code42 apps.

Why are we making this change?

We are removing support for legacy port 4282 to improve security.

Legacy port 4282 allowed Code42 apps to connect to storage destinations using non-TLS messaging. Beginning with the introduction of TLS messaging in Code42 version 5.4, Code42 apps started using port 4287 to connect to storage destinations over a Transport Layer Security protocol. While secure, non-TLS communication over port 4282 is not as secure as TLS communication over port 4287.
