[squid-users] Whatsapp web on Squid

[Andrew Wood]

Hi

Can anyone help me with Whatsapp web and Yahoo mail not working via a 
Squid proxy please?

The only reference I can find online to Whatsapp refers to SSL bumping 
which we are not using. Clients are explicitly configured to send HTTPS 
traffic to Squid on port 3129, but according to the Squid log Whatsapp 
server is responding with 403.


Likewise although Yahoo webmail works, accessing it via IMAP from 
Thunderbird is failing. This seems to be because it uses OAuth2 for 
authentication over port 443 and again Yahoos server responds with 403.


All other HTTPS stuff appears to be working fine. Is there a workaround?

Thanks

Andrew
