WhatsApp
Does not work in China
I needed VPN to make my proxy work. Architecture would need to be redesigned so that all traffic goes through port 443.
In the about section, this proxy only supports the default connection + chat. Currently media and VoIP are not supported through the proxy.
Whatsapp cannot connect successfully to proxy in China at all. Not related to media or Voip.
+1 In Iran the same. Any Idea how they recognize and block it? Maybe we can change some parameter to get it functional. With a new subject for selfsigned cert and new port, I've testet without any success.
Since it is working with VPN I guess China and Iran are somehow blocking the traffic.

I would redesign so that all data is routed via port 443. I do not think there is any easy fixes to this. I think currently blocking is easy because Whatsapp tries use other ports than 80 and 443.
I guess you are correct. I suppose somebody from WhatsApp should say his opinion about it too.
Are my proxies also blocked? https://whatsapp-proxy.com (Besure to copy-paste the IP with the port)
Would love to try find something to make them accessible
Thanks lot. Seems that specifying port will help. I tested these with ios and worked without VPN

@Christer-Ekholm @ydagnhienil, curious if you guys set up your proxies in China and Iran respectively, or outside those countries?
I don't think you can setup one in Iran, because then the proxy server can't reach whatsapp
@GewoonJaap Yes, that's what I wanted to verify. Curious how they detect that it is a WhatsApp proxy because the traffic especially on ports 80 and 443 should look like ordinary traffic and for sure they wouldn't know the proxy IP addresses.
Niceee! This works in Iran or any other country that blocks whatsapp?
I am asking a few people to test and report back.
@gary-RR That's very strange indeed. Because both ports are the standard for web traffic.. And traffic on both ports should be encrypted by WhatsApp + the local proxy SSL cert (prob only on 443??)
I guess it's just TCP traffic right? No http(s) traffic. Because I wanted to try hide my proxy behind a Cloudflare Tunnel/setup a Cloudflare worker, but only possible with http(s) traffic afaik
I set my proxy to Azure cloud north Europe. It worked when I enabled VPN but did not work without it. So I am pretty sure that China great firewall block it.
If it is not SSL (443) perhaps they eavesdrop and something in the payload gives it away (perhaps some reference to WhatsApp).

What happens if you start a little webserver, can you reach that one or also blocked? Maybe the block Azure IPs?
Interestingly enough, out of the following 3, two worked in Iran. (one user, mobile data, no VPN)
YES 141.148.228.97:82 NO 68.183.8.87:80 YES 51.14.190.56:5222
I am surprised because port 80 should be more likely to work. Is it the DO server that's blocked? Will add more observations as they come in.

Very Interesting! 68.xxx is indeed DigitalOcean. The first is Oracle Cloud and I don't know about 51.xxx
Does this one work: 64.227.75.24:82 It's also digitalocean
@gary-RR Can you give me a working server that offers 443? I haven't gotten around to set up one yet.
68.183.8.87:443 and 68.183.8.87 works China. I start doubting me first tests. I cannot verify my own server now
Ah okay, I guess that is because I haven't change the CN name. Gonna change it now.
