Ports for Firewall

My organization uses firewall to restrict traffic. We have whitelisted 443 port with ip adresses:
35.188.42.15
34.120.195.249
35.184.238.160
104.155.159.182
104.155.149.19
130.211.230.102
But still firewall is blocking sentry messages and exceptions. Which ports should be whitelisted to enable sentry send messages and exceptions?
