Will fail when encryption is enabled.
The issues was introduced where we started supporting the use of encrypted ports from the query. We were only using un encrypted port numbers always.
The design is to support
- only un encrypted port numbers when encryption was disabled
- both un-encrypted and encrypted port numbers when encryption was set to all
- only encrypted port numbers when encryption was strict
But after the change only encrypted ports are working in encryption mode all which breaks backwards compatibility.
