Hi Amos,

I have commented the line: "tls-dh=/etc/squid/ssl_cert/dhparam.pem"

And, it seems that many errors (SSL errors) in cache.log have disappeared.
I will confirm later if WhatsApp works from iOS/Android.

Thank You!

PS: I used this option (tls-dh, dhparam, etc..) following the official documentation of squid-cache.org for the "hardening" ... or "improve security", etc.
