Rule 2 is blocking HTTPS access (port 443) and has a priority of 500.
Changing Rule 5 (ports 50-5000) and giving it a lower priority number will allow access on port 443.
Note: 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.
