@Chinaski1 @TheHasagi to figure out what's wrong, we need to get the logcat log:
https://kb.adguard.com/en/android/solving-problems/logcat

It needs to be exported right after the issue is reproduced.

Eugene-Savenko · 2019-07-06T09:28:44Z

ameshkov · 2019-07-13T12:06:09Z

We cannot reproduce this even on the same test devices.

Here's what we need to troubleshoot:

Wait until the issue happens again
Get logcat: https://kb.adguard.com/en/android/solving-problems/logcat
Get AdGuard's own log files (settings -> advanced -> export logs)
Remember the exact time when it happened

patrickdrd · 2019-07-14T15:33:18Z

it happens to me too,
I'm attaching logcat and log files:

adguard_logs_3.2.95_1407_183159.zip

2019-07-14-18-29-42.txt

the time it happened should be around 18:25:
java.lang.RuntimeException: javax.net.ssl.SSLHandshakeException: Connection closed by peer

I restarted AG and connection was restored

I'm running latest nightly on local proxy (root) with cloudflare dns (regular)

Progress update:

We have logcat from 1889438

ameshkov · 2019-07-25T13:46:42Z

@AdguardTeam/support-team guys, next time please request this instead of logcat.

It contains all the necessary information + logcat. Besides that, we'll need to get AdGuard logs.

Also, we'll need to know the time when the issue happened.

Template:

To troubleshoot this issue, we need to get the additional logs.

When the issue happens again, please do the following:

Remember the exact time when the issue happened, we will need it to find the corresponding records in the log file.
Export AdGuard log: settings -> advanced -> export logs
Additionally, capture the system bug report after reproducing the issue. Here's the instruction.
Send both files to us, and please mention the exact time when the issue was reproduced.

ameshkov · 2019-07-25T13:47:19Z

I'm running latest nightly on local proxy (root) with cloudflare dns (regular)

Root is different. Most likely, AdGuard was killed by Android.

should I do something about them?

Nope, these are okay.

ameshkov · 2019-07-25T13:54:38Z

2228088

Too late to record the logcat:(

Please ask the user to do this:
#2842 (comment)

Considering that capturing Android bug report is not as complicated and does not require connecting to a computer, it'd be much easier to collect the necessary information.

I didn't say that AG was killed, but my internet connection did,
it has happened twice lately if I'm not mistaken,
very rare issue, but awfully annoying when it happens

After all, at another one deep study of the problem, we noticed unusual network behavior that told us where the possible bug has been hidden.
The first, unofficial bug fix has appeared in the Nightly 9. We interviewed the AdGuard community members who were most often exposed to this problem and all confirmed the fix is succeeded.
We hope the fix will be a success for you all, also.

dnovitskyi · 2020-05-06T14:24:57Z

User 2669879 reports that the problem has not gone away. They are running AdGuard 3.4 beta 1.
See support ticket 2669879 for detailed logs.

artemiv4nov · 2020-05-06T19:10:50Z

Got the situation from User 2669879, sent an email.

quyleanh · 2020-05-31T17:33:01Z

I still have this error sometimes...

Jinestic · 2020-06-02T06:21:04Z

Internet blocking issue still present on 3.4 stable. Yes, it's less prevalent compared to 3.3 but it's definitely not fixed.

Also, It's not actually related to switching connections between wifi/LTE because many time it blocks internet access even in same WiFi connection, it's like internet was working a minute ago now no application can connect to internet unless I go to Adguard manually, and disable protection and re-enable it. (quick setting widget turn off/on also don't work to gain internet access back)

I'm on POCO F1 but with custom ROM Android 10, so it's not like MIUI is shutting down adguard.
Plus Battery optimization is disabled
Running in Background allowed fully
Even allowed OOM adjustment via advanced setting with root

But issue stays. (Same issue was there in stock MIUI Android 10 as well, same setup as described above)

It's kind of random on daily basis but mostly happens after using device that has been in ideal for some time. Also, it doesn't happen right after waking up ideal device as internet works for sometime and then suddenly nothing connects ! So, manual reconnect is required to get Internet access back as described initially.

Don't know what kind of logs you'll need for this so let know.

quyleanh · 2020-06-02T07:29:34Z

@jineshpatel30 Your description is the same with me. I notice that the issue is not happened when using mobile data, it's seems only happen on wifi network.

Jinestic · 2020-06-02T07:33:12Z

@jineshpatel30 Your description is the same with me. I notice that the issue is not happened when using mobile data, it's seems only happen on wifi network.

I'm on WiFi for like 99% of time, so what you're saying is highly probable but I can't confirm.

quyleanh · 2020-06-02T07:50:07Z

@jineshpatel30 ok. Hope this issue is fix.

Jinestic · 2020-06-05T10:29:00Z

@jineshpatel30 ok. Hope this issue is fix.

Hey can you check whether internet blocking issue continues for you if you use "Proxy Blocking" method instead of VPN. (Auto proxy won't work without root but you can still setup manual proxy) Adguard will guide you through steps.

I have an Interesting theory through my experiment yesterday.

quyleanh · 2020-06-05T14:04:56Z

@jineshpatel30 I am checking now.
There is some work around for this, I think. You can try to pause and resume the protection from notification panel. I did twice and it worked.

I tried pause & resume few days back but some time that also doesn't work :(
Anyway give Proxy blocking a try, I'm using it for around 12 hours now without any network drop so far. See how it turns out for you and let them know here.

quyleanh · 2020-06-05T14:21:25Z

@jineshpatel30 is there any recommended proxy server?
Btw, the ads is not blocked well when I change to proxy mode...

Jinestic · 2020-06-05T14:30:40Z

I don't think so, It's local proxy so there's nothing like different proxy server. Tough, I think Manual Proxy doesn't work with mobile data, You'll need WiFi for manual proxy setup. For me it was auto configured since I have root but here's manual setup guide.
