Aim to sniff this domain: graph.facebook.com. However, cannot generate a valid certificate, may be because the expired date are before the creation date? I am not sure

What OS Version are you using? (Ex. mac 10.13)

10.12

Hey @van-tienhoang,

From what I see, the Proxyman Certificate has been installed successfully. You could see the Expires: it's 2024. If the installer was failed, it will present (Not Install)

I would have couple questions to investigate it:

1. Are you able to sniff HTTPS response from other domains (not graph.facebook.com)?
2. Which OS are you using? From what I see in Preference, It has Theme Tab -> It mean OS 10.14, isn't it?
3. Are you admin or non-admin user?

It turns out that this domain is supported SSL-Pining, which prevent mitm tools, like Proxyman intercepts data. Thus, we couldn't do anythings
