Bug Reports
#1

REPRODUCIBILITY (% or how often): 100%
BUILD ID = OS VERSION (Settings > About product): 4.3.0.12
HARDWARE (XA2, X10, X10 II, …): XA2
UI LANGUAGE: English UK)
REGRESSION: (compared to previous public release: Yes, No, ?): Yes

DESCRIPTION:

Upgrading my phone to 4.3.0.12 results in an unstable internet connection that keeps on saying “connecting” and “Limited Connectivity” in a loop.
The internet connection is therefore unstable and I can’t browse the internet properly .
I thought this might be an issue with the setup of my device, so I reset my phone and upgraded it up to 4.3.0.12 without changing any settings or installing any apps.
I can confirm that the version prior to this doesn’t have this issue.
This issue has been seen after updating to latest version with my original software setup on the device and also after the reset.

Some other information:
Before updating to 4.3.0.12 I saw “Remove or revert the following packages, as they may cause problems during update”
This message was shown both times before I performed an update to 4.3.0.12.
The list of software to remove was very long.
The mobile network is UK EE, I have tried this around several sites around London and Manchester.

The hardware is an Xperia XA2
A (blurry) video showing this fault can be seen here: https://youtu.be/qe6Rx6KYHDM
There is also common random vibrations that the phone does frequently

PRECONDITIONS:

Upgrade to 4.3.0.12

STEPS TO REPRODUCE:

  1. Upgrade to 4.3.0.12
  2. Observe bad 4G

EXPECTED RESULT:

Stable 4G connection as per the last version

ACTUAL RESULT:

See SailfishOS update to 4.3.0.12 unstable Internet - YouTube

Hi, I do use OpenVPN on my XA2 with 4.3.0.12. do you have a chance to see the logs on the server side?
It might help to manually adjust the mtu according to the servers preferences.

workaround: If you are using an .ovpn configuration file the first thing could by to reinstall the network. This is done in a few seconds and might do the job.

This is a clean install without any VPN setup

Just to avoid misunderstandings. You need to set up a VPN connection in order to use OpenVPN.
You might enter settings like

  • protocol,
  • host,
  • port,
  • cypher,
  • ike version,
  • compression,
  • certificate location

etc. manually or use a configuration file.
These normally end with “.ovpn”.

If you use such a configuration file it would be very easy to delete the connection and reconfigure.
If not adjusting some settings as the MTU might help.

If you have access to the server’s log files it should be pretty easy to analyse the problem.

:thinking: Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhh!
Now I get it! :smiley:

The headline is wrong!

"Open VPN not connecting"

should be

"Mobile Network not connecting"

Do you want me to change the subject or would you do that maybe yourself?

I’ve changed it, I’m not sure why the title said anything about VPNs
