Push Notification Preview images doesn't show while on LAN

[hadberz]

Many thanks for this! While your issue was slightly different than my own, this bit got me to where I can finally get images/GIF in my Push notifications. For me, my mobile devices are always on VPN when away from home, using an always on Wireguard setup. So, they are always on my LAN, never WAN, and I was unable to receive images/GIFs with the Push notifications whether at home or out and about. Simply replacing the WAN IP with my Local IP and unchecking the "Refresh external IP..." did the trick.

I use openvpn and this solved it. Thank you!

I just want to add that I had the same problem but the solutions in this thread didn't work for me. What I learned was that with Tomato firmware, NAT loopback under Advanced -> Firewall does NOT work if CTF (Cut-Through Forwarding) is enabled under Advanced -> Miscellaneous. Un-checked this box, rebooted the router and voila, push notifications with previews work! Note that some have said CTF is needed for higher internet speeds but my Spectrum base plan of 300mbps remained the same with a speed test even after CTF was disabled. Hope this helps someone.
