No push notifications when connected to wifi

Hi ,

I have a ZTE MC801A router which i recieved from three when i signed up to the 5g hub internet when i moved into my new house. Since then i have not recieved push notifications through to my phone, neither has my girlfriend. When we disconnect from the wifi and to 4G roaming we recieve all the notifications we should have at once. This also means our Google Hello doorbell does not work - it does not send notifications through on home when we are connected to wifi and also means we do not hear the doorbell as it wont send a chime through to the Google Mini speaker. Ive tried port fowarding Port 5228, reset to factory settings, enabled UPNP and reset the Google Home devices with no luck.... Any idea?

Phoning three on 500 from my three mobile I got the adult filters removed. No I get all my notifications. This is probably why it's affecting phones now as well.

Hello chaps @maxf @JonathanB @macdog hope you all had a good Christmas - any update on a fix for this? From what has been said previously it sounds like Google Firebase Cloud Messaging is being blocked at some level which stops push notifications coming through

Hey, same to you!

I took the hub away with me and notifications seemed to work. I just got back yesterday and notifications seems to work at home now too!  I will test properly later as I'm not using the hub.

Incidentally, when I was having the problem I did some connectivity tests to the published FCM addressed and all seemed fine, which is strange!

Just back from a few days off. Nothing new except I noticed I do get notifications when my phone is on a VPN. I don't really know what that means but it might help network engineers diagnose further.

I managed to partially fix it. I forwarded ports 5228-5230 and 443 through to each phone and device assigning a static IP to each one. This has allowed notifications through. The only issue is there is a maximum of 10 rules on the router which makes a maximum of 5 devices (2 rules per device for both port ranges). This has allowed notifications through, however it does not sort the Google hello doorbell notifications and should not be the fix, Three should be better than this and have a permanent fix at Thier level but may give an indication as to the issue

Thanks. Very interesting. I think we should just create a new post with a summary of what we've found. It'll be simpler for Three to investigate. What do you think?

More investigation: I took my router to another part of London and it worked. So it's working in E1, but not in SE16.

So it appears to be something with the tower. @macdog , @GnortsMrAlien - Do you happen to be in the same area by any chance? Nearest cell to me seems to be: https://www.cellmapper.net/map?MCC=234&MNC=20&type=LTE&latitude=51.49326520665156&longitude=-0.04417...

I'm in North East London. Can't seem to find a nearby three 5g tower on cellmapper though.
