It’s strange. My whatsapp can’t load image sent by others on my iOS.
Can you confirm the config you have here - what policies do you have set?
You probably need to add a Do not Decrypt rule for WhatsApp and other cert pinning applications.
Skip inspection for groups of applications · Cloudflare for Teams documentation
I had the same, not only Whatsapp, but also my banking app and other apps (Tesla, …) didn’t work anymore. Next to what @cs-cf mentioned, you can also disable TLS Decrypt in Gateway > Policies > Settings
By the way, @cs-cf , is it possible to add manually an application instead of using the Cloudflare list of certificate pinned resources? My banking app is not in the list for example… (or is there a way to submit apps which rely on certificate pinning?)
I’ve managed to resolve this by whitelisting WhatsApp subdomains!
Gateway > Policies > created a policy to Allow Whatsapp hostnames
