We’ve just upgraded from HAP 1.7 to 2.0.8 and a small percentages of our requests have started failing. After a TCP Dump, we noticed that the Request URL was:
GET https://redacted.host:443/ HTTP1/1\r\n
Host: redacted.host
These requests were returning a 400 Bad Request, but on 1.7 they worked just fine. So I broke out telnet and tried it manually.
FYI I had to remove the // from the URL’s in the RequestURI to pass the inspection of the post, it thought I was trying to share URL’s.

The configurations are basically the same, but this one type of request is failing. Does anyone know a potential change between 1.7 and 2.0 that could cause this? Setting change? Anything?
