Outblund push notifications being blocked

[MJBritton25]

I have fttp broadband, and i also have an intercom system connected to the wifi. This does outbound google push notifications . It stopped working over a week ago, when no changes had been made on the network. I wiresharked it and can see its getting blocked somewhere.  I connected the intercom to a hotspot and the notifications work fine.  So, i did a factory reset of my smarthub and then notifications worked for about 36 hours. Now they have stopped working again. Any ideas? My suspicion is some sort of bt update on the router.

Update - I did another factory reset and its working again.  So I suspect its either BT pushing config out, or a traffic shaping issue.

More likely an IP address issue for some odd reason. Every time you reset you will be getting a different IP address.

Next time it stops working - I'll try assigning it a new IP.

I think you might be right tho - but what that could  be, who knows.  Something at the router or BT end of things.

You can't assign a new IP but you can check if it has changed.

Ahh you mean the IP of the router, not of the device.  Got ya.

Yes, rebooting or  disconnecting your router will usually result in a different dynamic public IP address.

The interesting thing on that is that when it wasnt working, I

• Connected my laptop to the same wifi
• created a hotspot on my laptop
• Connected the intercom to the laptop

Then push notifications worked, whilst the intercom was connected to my laptop's hotspot. 

All the time, the routers IP would of course had stayed the same.

Weird.
