Your allow to 80 to wan might trigger first? Why did you not just let pfsense create the wan rule for you wen you created the forward? So the rules would be linked. You don't want to allow 80 to your pfsense wan IP, you want to allow 80 to be forwarded to your box behind pfsense. That wan rule says hey if you want to talk to my wan IP on port 80 - its allowed.
If it sends traffic to pfsense WAN address first - is there anything listening on pfsense on 80 on the wan interface - if not that explains your closed result.
If you want to send 80 to 8099, which seems odd normally it would be the other way because isp blocking 80, etc..
But your rules would look like this - see attached. Notice the linked symbol on the forward rule.
I never understand why users change the default when doing a forward which is to allow pfsense to create the associated wan rule. I would start over, remove that rule to 80 and 443 you created and let pfsense create the wan rule when you create the forward (default).
Also quite often web server firewall needs to allow traffic from internet, quite often it only allows traffic from the local network until its opened up. And you sure you listening on 8099 on the webserver? You can access that from the local network?
