Technical Tip: Unable to send/receive images and documents on WhatsApp

[mramalinga]

Description
This article describes how to resolve the problem of not being able to send/receive images and documents on WhatsApp.
Solution
If an application Control profile is used in the policy, ensure that all the WhatsApp signatures are set to 'Allow':

Note.

In this case, SSL deep inspection is required in the policy.

CLI configuration.

# config application list

edit "Allow_WhatsApp"

# config entries

edit 1

set application "28057" "37371" "40698" "39999" "49971" "49970" 

set action pass

end

end

end

If a WebFilter profile is used in the policy, verify if the below URLs are allowed (this example is based on the requirement to block 'Instant Messaging' and 'Web Chat' categories and allow only WhatsApp traffic):

CLI configuration.

# config webfilter profile

edit "Allow_WhatsApp"

        # config web

            set urlfilter-table 1

        end

# config webfilter urlfilter

edit 1

            set name "Auto-webfilter-urlfilter_zj9stazr3"

        # config entries

            edit 1

                set url "*.whatsapp.com"

                set type wildcard

            next

            edit 2

                set url "media-sof1-1.cdn.whatsapp.net/*"

                set type wildcard

            next
