Missing Push-Notifications via VPN

domubpkm · 27 Apr 2019, 11:09

@thilov Hi. I can only say that when i use a VPN installed with VPN editor on any UT phone, i get DEKKO 2 notifications.

A Former User · 27 Apr 2019, 11:15

@domubpkm Are you also using your own VPN Server?

domubpkm · 27 Apr 2019, 11:32

@thilov NO it's not my own VPN server. I didn't well read your post, SORRY. Is it a wrong idea : maybe could you do something with VPN editor and your own VPN ? I don't know.

hummlbach · 27 Apr 2019, 11:42

signal uses notifications only locally (thats why you need to have it running in the background) no push server involved there... my companies guest wlan also blocks uts notifications. Maybe @Flohack or @Krille can shed some light on how to investigate/analyze/solve that...

A Former User · 27 Apr 2019, 12:08

If I'm connected with wlan (same network) I get notifications.

Can you route to push.ubports.com while on the VPN? Are any outgoing ports blocked for addresses on the VPN?

Ping looks fine.
I have a standard PiVPN setup without any modifications. I didn't block ports and even don't know how to do this.

A Former User · 28 Apr 2019, 21:21

Well, I also use Pihole. I will add push.ubports.com to the whitelist and test it tomorrow.

A Former User · 29 Apr 2019, 09:15

Adding push.ubports.com to the Pihole's whitelist doesn't help.

I just recognised, that I don't get any mails (only tested with dekko 2) after disconnecting the VPN even if I open the app.
Enable/disable fligtmode just helps for a second. I have to reboot the phone to get back to the expected bahavior.

There should be I think ~/.cache/upstart/ubuntu-push-client.log can you check it please?

@thilov It looks like you've got a somewhat cropped version of that, but it does seem there is some errors in there with a little more info that didn't get included in your copy/paste.

A Former User · 30 Apr 2019, 20:38

@dobey I fixed my copy and paste mistake.

A Former User · 30 Apr 2019, 20:45

And this is what I did/got:
22:00 start VPN
22:04 sent test mail and telegram-mail
22:08 opend Dekko2
22:12 opend Telegram and got Dekko2-push
22:16 stopped VPN and got Telegram-push
22:19 got same Telegram-push again
22:20 sent testmails again and got the push

dobey · 1 May 2019, 14:18

OK. First, to clarify, dekko does not use push notifications. It has another daemon running locally which polls to download e-mail, and then uses the local push notifications API to pop a notification, but it does not go through the push.ubports.com server.

Telegram does send notifications via the push server, but even when working properly, can be very slow to arrive.

As you see in the logs, there is some connectivity issue when switching between the network interfaces, and it can take many minutes before the client reconnects to the server. I would say that to test it properly, you need to stay connected to the VPN for quite some time, and not use the applications on the device while testing if push works, but instead send some telegram messages to your user on the phone, from a different account on a different device.

If dekko is also having issues, the cause may be somehow related as it's with network issues, but it is probably a separate fix that would be needed, if the problem is in the client software rather than network config.

A Former User · 6 May 2019, 09:50

I tested ProtonVPN with similar results.

Is a hardware issue possible? Sadly I doesn't have a second UT device for more testing.

@thilov said in Missing Push-Notifications via VPN:

I doubt it's a hardware issue. It's most likely some configuration issue preventing connection to the services when you connect to VPN.

You don't need a second UT device to test sending messages via telegram. You can have someone else send you messages (probably after 20 min or so), or use a reminder bot like https://t.me/SkeddyBot to schedule a few reminders.

Also note however, that Telegram push notifications can be slow on the Telegram side at times, so to test it would be best to leave the phone connected and not use Telegram on it, for at least an hour, and have multiple reminders set to be sent to you over that time period.

Another option is to install and set up https://caxton.herokuapp.com/ to send push notifications from a PC to test.

A Former User · 5 Jun 2019, 13:04

I tested that at the weekend.
I rebooted the phone, connected to vpn and sent a telegram message from my wife's phone (a message of the UBports News Channel came also in this time).
I waited 5! hours and nothing happend. The .log was similar to the one I posted before.

A Former User · 7 Dec 2021, 13:59

I just did what @circ did here: https://forums.ubports.com/topic/2693/where-are-vpn-logs-solved

I started the log, started the vpn and opend telegram

I can't find any error but I'm just a noob. Might someone tell me if something can be found out here?

@thilov I am not sure if your issue is solved, but I think I noticed something similar. When you connect to the vpn and especially use a kill switch, the ubuntu push notification ( and also pantalimon and may be other processess unrelated to notifications) are still associated with the old gateway and not the VPN gateway. You can can do the following:
sudo netstat -tunlpaw
and look for the processess ESTABLISHED with your old gateway address (for ex: 192.168.1.xx)
Then use sudo kill -HUP xxxx where xxxx is the PID number of the process identified in the previous process.
This should reassociate the process to the new gateway. If not try sudo kill xxxx without -HUP option. Notification process will reassociate after a while. Hope this helps.
