Hi

EDIT:

I've noticed that when my SailfishX is connected to my home wifi sometimes it takes hours until a message someone sent to me over whatsapp arrives. And, when going outside the range of that wifi (device switches to mobile), I receive any pending messages.

Lately, when I am expecting messages, I just tap the wifi down -- and if there are any incoming messages it takes like 2 seconds to get these received.

I used to think that switching between the networks is the "cure" there, but today's experience with WhatsAPP Web gave the thought in subject line:

While using WhatsAPP Web when SailfishX is on that wifi, usually around 15-20 minutes I get 'You phone is not connected' message displayed on web browser (or something similar, I get it in finnish. so...).

I tried some tricks, like pinging 9.9.9.9, which did not help.

Then I disabled wifi -- and, unsurprisingly, the "phone is not connected" disappeared.

And ... THE CONNECTION HAS BEEN ALIVE EVER SINCE (until end of the day due do voluntary disconnect).

¿Has anyone else there experienced the same lately?

¿Does anyone have any idea what could be the culprit?

I remember it is just not with this particular wlan access point, but at least with one other (of the same brand).

I am currently running 2.1.4.14 (Lapuanjoki) on F5121, WhatsAPP 2.18.91

The problem has been there since 2017-10 when I bought the device.

There is somewhat similar thread, https://together.jolla.com/question/122636/bug-android-messaging-whatsapp-messages-arrive-late/ (last update over a year ago) -- it could be something related to android layer -- OTOH something between Xperia X and some particular wifi devices.

(And, don't nobody not suggest changing to another messaging solution -- I'd like to, but I'd be alone there ;/)

just for the record, i have the same problem. It occurs only on the Xperia X and since 2.1.4.14 (Lapuanjoki). And there is a cumulation when the mobile communications network is weak (< 3 G).

Hi.

As a preliminary test, I'd suggest to try another Android App when WhatsApp fails, for instance Mozilla Firefox.

If you can surf the web normally it's WhatsApp fault, if you can't there's something odd with your connection (maybe the AP's configuration)

As far as I can remember (I quit WhatsApp in early 2016) the client connects to a regular https web server, something like https://s.whatsapp.com ....

Good luck!.

Regards.

This is good idea!. I'll test when I get to that particular wlan.

EDIT:

  • List item Waited 30 minutes w/o touching Browser where WhatsAPP Web was the only thing running. Then started using it -- got message 'Phone not connected'.
  • Started Chrome on Xperia X and surfed a bit -- after a while WhatsAPP Web started to work normally.
  • What this could mean -- have to think this first (and do all kinds of experiments)...

For the Xperia X versions, I've had this problem also before 2.1.4.14.

Noticed just now:

  • Tried to scan the QR code for WhatsAPP Web. It just could not get it. After a while got a notice 'check your internet connection'.

  • Launched Chrome, browsed a bit and then tried scanning QR code again. Failed again

  • Disconnected Wifi... and scanned QR code again when on 4G. Success in less than 2 seconds.

Based on this whatsapp does IP communication somewhat differently than Chrome. Have to see options how to e.g. tcpdump this...
