NethServer Version: 7.7.1908
I have a number of sites running NETHSERVER and they all have a similar complaint. A number of users battle with sending and receiving whatsapps using the app on their phones. They will send a message and it will take a very long time to send (if at all) unless they switch off wifi and use their data.
In the squid access log I am picking up entries like this:
1578289035.725 30103 192.168.1.23 TAG_NONE_ABORTED/000 0 POST http://c.whatsapp.net/chat - HIER_NONE/- -
Can anybody give me an idea as to why the firewall/proxy/content filter would be stopping throughput of WhatsApp?
Thanks in advance.
