Add KB for Error Message "HA could not be enabled" in HA Setup

Thank you for this feedback, philbert,

Did you configure your primary device via QuickHA or via the interactive mode? Did you also follow the steps in docs.sophos.com/.../index.html

I've used "Interactive mode".

yes, I followed the steps, but they do not explicitly state the HA Link has to be UP and Peer Device must be reachable.

Thank you for your confirmation, philbert.

I am confirming with a colleague if we just need to update our documentation and include a note about the error instead of creating an article about it.

I'll inform you once I have the reply.

Hi philbert,

The networking requirements section of our Sophos Firewall online documentation is now updated with the information you shared.

Please continue to share with us any information that you think needs to be added or updated on our documentation or knowledge articles.

Thank you :)
