As of version 1.3.11, a green dot has been added to the interface of Jaxx as an indication whether you are connected to the internet. Once you lose connection or you have a weak internet connection, the green dot will turn red or will fluctuate between green and red.
The green dot can be found beside Menu icon on the upper right hand side.
The result of having red dot is inability to make transactions or initialize wallet.
To have optimized experience with Jaxx, we recommend making sure the dot is always green by being on strong internet connection, not using VPN/Firewall/Tor, or receiving mining rewards.
