HTTPS uses port 443.
Rule2, with priority 500, denies HTTPS traffic.
Rule5, with priority changed from 2000 to 401, would allow HTTPS traffic.
Note: Priority is a number between 100 and 4096. Rules are processed in priority order, with lower numbers processed before higher numbers, because lower numbers have higher priority. Once traffic matches a rule, processing stops. As a result, any rules that exist with lower priorities (higher numbers) that have the same attributes as rules with higher priorities are not processed.
