Unencrypted HTTP protocol detected over encrypted port?

0

I see in my witeshark the below msg. Unencrypted HTTP protocol detected over encrypted port, could indicate a dangerous misconfiguration.

What does it mean?

Port 443 has been assigned by IANA for transport of HTTPS traffic. When detecting unencrypted HTTP this is a possible sign that the intention was to use HTTPS, but possibly a misconfiguration, or some other reason, lead to serving unencrypted HTTP over port 443. As people somewhat expect port 443 to carry encrypted traffic this warning is generated to alert the network or system administrator of possible problems.
