Why do I get an "SSl peer certificate or SSH remote key was not OK" error when attempting to reactivate my license?


  • I want to reactivate my license.
  • I am receiving this error: "SSl peer certificate or SSH remote key was not OK"


This is usually due to a connectivity issue between your machine and our license servers. It can be resolved either by adjusting some of your settings, or by performing a Manual Activation.


The reason you are not getting the right SSL certificate or SSH remote key is due to one of the following issues:

  • You have a firewall or proxy in place which is interrupting your connection to the license server. Please try allowing these ports in your settings: 80 and 443.
  • You have an anti-viral software that is blocking the connection. Please try disabling this and seeing if the Editor will work.
  • You have a weak or intermittent Internet connection - this is less likely than the points above.

More Information

If this does not solve the problem you may need to perform a Manual Activation.

To perform a Manual Activation:

  • Temporarily switch off your Internet
  • Run Unity and you will be prompted to initiate the Manual Activation process.
  • Follow the steps shown in this document.
