Line messenger not showing pictures.

As I using Application control feature on Sophos UTM 9.605.

I got an issue with Line messenger(PC) after do upgrade this software to version 5.19, It doesn't show any pictures during opened behind firewall network.

Tried to figure out, I found Line application accessing to these URLs below

a104-103-68-203.deploy.static.akamaitechnologies.com    https    SYN_SENT                                        
a184-50-28-92.deploy.static.akamaitechnologies.com    https    SYN_SENT

a23-53-163-24.deploy.static.akamaitechnologies.com https    SYN_SENT
a23-194-40-105.deploy.static.akamaitechnologies.com    https    ESTABLISHED                                        

Assume server changes and have more than this, then it made some of pictures still not show.

So how can I setup the firewall rules to make Line app working properly? Thank you.
