HTTPS sites no longer load on my Android after installing cert to truststore I have a rooted Android 4.3 JellyBean. I was testing something and trying to install the certificate for Charles Proxy so I could sniff some SSL traffic. I was able to push the Charles certificate to /system/etc/security/cacerts and this allowed me to do what I wanted. However, ever since I did this, my browsers no longer load HTTPS sites. For example, Chrome gives me the "Your connection is not private" message. 

Also, and not sure if this is normal, but when I look in Settings > Security > Trusted credentials, there are no System Certificates listed.

How can I fix whatever I did?
"Whatever you did", you removed all of your trusted CA's (Certificate Authority).

Unfortunately I cannot help other than to say you should have well over 50-60 trusted CA's in that list (where you have none).
