Hello developers. The updater has been unable to connect to the internet since the first day of my purchase of GSX Pro. Initially, I thought the connection to the server was blocked by Great Firewall so I circumvented it by using VPN. But today after I did a tcpdump on my home router and analyzed the captured packets using Wireshark, I was surprised to see that it's actually blocked by Cloudflare
Here are the request and response under my home network

Could you please check your firewall or WAF to see if there are any rules blocking connections from my home network?
