Hello @liangchenhe55!
Thank you for contacting us. We are looking into this problem and trying to reproduce it. Could you please tell, is this problem happens only on one specific device? Or on all your devices?

ichenhe · 2020-11-17T00:45:03Z

@vvechkanov There are two different types of exception.

1.SSLHandshakeException: You can reproduce it easily with any types of Wear OS emulator in Android studio.
2. java.net.ConnectException: May be on any Wear OS real devices. But only XiaoMi Watch and Mobvoi TicWatchPro are tested.

vvechkanov · 2020-11-17T12:08:18Z

@liangchenhe55
We tried several computers with Wear OS emulators in different networks. All of them working with App Center correctly. No network exception, analytic data is sending correctly. Could you please try to check SSLHandshakeException exception on some other computer? May be some environment cofiguration cause this issue.

About 'java.net.ConnectException' issue on real device, we are working now, on reproducing it on different Wear OS real devices.

ichenhe · 2020-11-17T15:52:53Z

@vvechkanov I have tried an other computer but the problem still there. I don't think it is an host computer releated issue since my phone emulator is fine,

I will try an other computer in the other city and network environment tomorrow and share the result with you.

ichenhe · 2020-11-17T16:45:13Z

I have captured the tcp packages on emulator with tcpdump. So it seems that the server did not send the pub cert but rest the connection after the emlator sent TLS Hello.

ichenhe · 2020-11-18T04:34:17Z

@vvechkanov Unfortunately, the emulator in an other city and network environment failed again. May be we can find out something from the tcp packages above?

Hi @liangchenhe55!
Thank you for checking this on an additional machine. This problem is not reproducing on any of our machines, that's why I asked you to check. We a trying to reproduce it in some specific environment and analyze the logs you provided to understand the reason, why this exception happens. But unfortunately, we need some additional time. I am sorry, but I can assure you we are working on investigating this problem.

ichenhe · 2020-11-20T10:02:52Z

@vvechkanov copy that, thanks. I also find some real devices have no problem. However those devices belongs to our users so we can not get it and do some analysis. I am trying more models of devices and more network envs.

russelarms · 2020-11-25T10:21:41Z

Hi @liangchenhe55, do you still experience the issue?
You've mentioned that retrofit2 works for you on Wear OS. Can you access appcenter api endpoint through retrofit2 (not using the App Center SDK) on Wear OS? Here's the quick guide on Appcenter API: https://intercom.help/appcenter/en/articles/1841885-how-to-use-app-center-s-api

Also is it possible to try the SDK with a proxy?

ichenhe · 2020-11-25T16:28:49Z

Hi @russelarms , yes, the problem is still there.

I tried to GET https://api.appcenter.ms/v0.1/apps/{owner_name}/{app_name}/analytics/versions shown in the docs with Retrofit2, it worked fine. But I noticed that its domain is different from SDK (in.appcenter.ms).
It difficult to set a proxy on Wear OS. Instead I set it on my gateway router and it solved the problem.

I apologize for my carelessness since I once said that there is no problem on the phone, because my phone usually runs an proxy, but it still a problem. It seems that in.appcenter.ms is blocked (or not stable enough) for some reasons in few regions in China mainland. This question is very tricky and may need the wider team to handle.

For the sake of caution, I tested on some servers with better network environments. e.g. Alibaba Clould Shanghai Node, Tencent Cloud Shanghai /Beijing Node. Run command curl/wget https://in.appcenter.ms. More than half the chance of failure.

[root@VM-0-2-centos ~]# wget https://in.appcenter.ms
--2020-11-26 00:24:12--  https://in.appcenter.ms/

russelarms · 2020-11-26T09:10:53Z

I apologize for my carelessness since I once said that there is no problem on the phone, because my phone usually runs an proxy, but it still a problem.

@liangchenhe55 As I understand it's not the case for the Wear OS only, you have the same problem on the phone if you turn off the proxy, right?

ichenhe · 2020-11-26T09:16:22Z

@russelarms right.

russelarms · 2020-11-27T12:19:21Z

@liangchenhe55 we've moved our endpoint to another IP pool. Could you try again?

ichenhe · 2020-11-27T14:39:06Z

@russelarms Now the data can be sent successfully in some cases, but it will still fail in some cases with the following errors:

javax.net.ssl.SSLHandshakeException: Connection closed by peer
java.net.SocketTimeoutException: failed to connect to api.appcenter.ms/52.138.116.79 (port 443)
java.net.SocketTimeoutException: SSL handshake timed out

May be I can set up an VPN for you to debug this problem. If necessary, please give me an email so that I can send the VPN account to you.

russelarms · 2020-11-27T14:52:40Z

Our engineers are working on investigating this problem, but there's not much that we can do apart from changing the IPs at the moment.
Some middleware seems to block some SSL connections in China.

ichenhe · 2020-11-27T14:57:37Z

Copy that and thanks. I am glad to provide any assistance and information at any time.

russelarms · 2020-12-02T08:00:40Z

java.net.SocketTimeoutException: failed to connect to api.appcenter.ms/52.138.116.79 (port 443)

Hi, @liangchenhe55! Another question just to be sure that we are on the same line:
I see you've tried App Center API (api.appcenter.ms), but we've moved IPs only for in.appcenter.ms (which is used by SDK). Have you checked the problem with SDK or only with App Center API?

ichenhe · 2020-12-02T08:09:21Z

Hi @russelarms , yes. I tried the SDK (v4.0.0) on the 27th Nov. UTC+8.

At the same time, the test code for api.appcenter.ms is retained. So this domain name also shown in the log. It can be concluded that the api.appcenter.ms is not very stable, just the same as in.appcenter.ms.

ichenhe · 2020-12-02T08:15:20Z

Maybe the same problems:

mzekrallah · 2020-12-02T14:16:12Z

I think we are getting the same issue here (but not a 100% sure) (we are in Jordan) .. also not sure if its related to our upgrade to major AppCenter SDK v4.0 (we were on old 2.1.1) but we're definitely not getting lots of crash reports and when investigated, started seeing these in the logs:

Hi @mzekrallah, how often do you see these errors?

DmitriyKirakosyan · 2021-04-27T10:52:43Z

Due to country specific policies and laws, we cannot guarantee that App Center works in all countries. For some users in China region, Analytics and Diagnostics SDK data may experience significant delay or not make it to our servers based in the United States.
Since we have not heard any new reports recently, I am closing this issue.
Please feel free to reopen it if someone faces a similar problem again.

ichenhe · 2021-04-27T11:01:28Z

@DmitriyKirakosyan Thanks fou your work and I'am sorry to hear that. Maybe Microsoft can optimize the routing by, for example, CDN. Of course, I know it's a big project. If things get worse in China such as google(you know 😞 ), I will reopen this issue.

Hello @AbdullahJaved-dev, according to AppCenter Services Status page - all services works as expected. Most likely your connection issues are related to your location.

how to custom the dns of in.appcenter.ms ?

I found that the IP I got in mainland China is 93.46.8.90

But if I look it up in dns.google I get an ip of 40.70.161.102

40.70.161.102 is work for me
