Description
Describe the bug
I am trying to get the version of some servers using nmap -sV -p 80. I know they are running Squarespace, but nmap returns me it is an RTSP service most of the time. There are few times when it returns it as HTTP, but not very often.

Research direction
Start by reproducing the report with nmap -sV -p 80 www.squarespace.com on the mentioned 7.80 and 7.91 versions, recording whether the service is identified as HTTP, RTSP, or SIP. No source file or test is named; investigate the service-detection path and use consistent HTTP identification as the completion criterion.
