Gateway log filled with "No Client Endpoint Idenfitication Algorithm" warnings

Hey folks,

I’m supporting several gateways in a single organization, all on 8.0.7. About half of them are recording the following errors, generally multiple times a minute:

I’m hoping someone has seen this before or can advise me where to start with addressing the issue. It’s filling several logs and I am unfamiliar with this specific error. As far as I can tell, the servers are not utilizing any SSL.

Many thanks!

Edit: After speaking with support, it seems as though it is a gateway network bug in 8.0.7, and upgrading should resolve the issue.
