The unexpected HTTP code '400'
Adding the IP address of the Node in binding of any website causes the error:
When adding this IP address to binding, I got the following error:
Binding information 'IP:80:' is unsupported with dynamic mode. The Windows Process Activation Service (WAS) restart is required to register that binding.
The behavior was considered as internal software issue #PPA-2327. The latest Windows updates break IIS bindings.
The fix is included in Plesk Automation MU#21.
Install latest PA updates according to the article.
