[Android] "Nebula keeps stopping" #46

dmanriqu · 2021-07-31T22:05:25Z

In the Android app, after configuring and trying to connect I got a message that says "Nebula keeps stopping." I'm using Android 7.1.2 on a Motorola Moto Z. I'm pasting some logcat output in case is useful:

I'm experiencing the same warning dialog but potentially for an unrelated issue - it seems Nebula uses all of the phone's RAM? When I launch my browser and try to load content from a Nebula IP I'm sometimes returned to the home screen, my browser is killed, my music app is killed (audio stops), and Nebula has disconnected with the dialog "Nebula keeps stopping". It feels like a resource issue if it's causing other apps to crash? Not sure how to debug since this is stock Android 9.0

waldner · 2022-05-05T18:44:11Z

Same here, Android 8.0.0 on a samsung galaxy A3. Configuration can be done successfully, but as soon as I try to connect the app repeatedly crashes.

johnmaguire · 2022-11-22T22:51:37Z

@dmanriqu @heyheyhello @waldner We just released a new version, v0.2.0, which includes some bugfixes for stability on Android. Please let us know if you continue to have issues.

waldner · 2022-11-24T09:58:14Z

Nothing changed for me even with v0.2.0.

johnmaguire · 2022-11-24T15:45:28Z

Nothing changed for me even with v0.2.0.

@waldner Thanks for trying. After the crash, if you click on the site and then "View Logs" do you see any output?

Are you able to obtain logcat output of the crash by chance?

Hi @waldner - thanks for the logs.

Are you seeing any errors reported for the site? Would you be willing to share the raw config? You can view it by tapping on the site, then "Configuration," then "Advanced" and finally "View rendered config."

No message on any of the lighthouses when trying to connect from android.

jasikpark · 2022-11-30T18:52:54Z

have you had it connnect before? can you try setting up a lighthouse that has a fixed IP rather than using the redirection of the DNS hostname?

b177y · 2022-11-30T22:04:15Z

same issue here, using Android 9 on Moto G6

atdotio · 2022-11-30T22:22:23Z

Same behavior with Android 12 on a Motorola G Pure. Tried with a static IP as the lighthouse as well. No change in behavior. My configuration is identical to the one posted above with the obvious exceptions for the certificates/keys and lighthouse host/IP.

waldner · 2022-11-30T22:35:01Z

I never got it to connect.
And using IPs instead of DNS names for the lighthouses does not help unfortunately.

jasikpark · 2022-11-30T23:22:49Z

do you have any other vpns running at the same time? just for a sanity check ;p

atdotio · 2022-11-30T23:25:18Z

Definitely do not have another VPN running at the same time during my tests. If I do, it instead presents a dialog telling me to grant Nebula VPN permissions when prompted (for what it's worth, it does nothing of the sort).

Ke1i · 2023-02-15T06:47:22Z

A bit late to the party but here I am :)
I'm running Nebula version 0.2.0 on an m8 powered by DivestOS 18.1 (Android 11) and Nebula keeps crashing when I try to connect. The VPN icon appears briefly then disappears as you can see from the video below.
Here's my config file:

I couldn't catch anything on Scoop but I've attached a logcat, together with the logs from the app.

are there any new theories in this regard. I've just setup a lighthouse an added my system and am running into the same problem. I intend on trying to poke at it this weekend to see if I can't get somewhere with this.
