Web server problems

[ferrebam]

Hi,

Both the docker version and the version with java binary, the web server does not respond, the shortcuts to the functions and a solid color background are displayed but it does not allow interacting with the environment.

In the application logs, it seems to show some kind of error but I don't know how to interpret it:

2021-09-19 23:40:18.237 INFO [https-jsse-nio-8003-exec-7] r.m.k.s.UserSessionListener : User successfully authenticated: UserInfo(id=1, timestamp=2021-09-09 18:17:58.104, createdBy=null, username=admin, name=Admin, phone=null, admin=true) 2021-09-19 23:40:20.848 INFO [MessageBroker-2] o.s.w.s.c.WebSocketMessageBrokerStats : WebSocketSession[0 current WS(0)-HttpStream(0)-HttpPoll(0), 0 total, 0 closed abnormally (0 connect failure, 0 send limit, 0 transport error)], stompSubProtocol[processed CONNECT(0)-CONNECTED(0)-DISCONNECT(0)], stompBrokerRelay[null], inboundChannel[pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0], outboundChannel[pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0], sockJsScheduler[pool size = 3, active threads = 1, queued tasks = 1, completed tasks = 1]
I have tried adding a device and apparently it initiates some sort of communication but causes an error anyway:

2021-09-20 18:00:12.993 INFO [pool-1-thread-799] r.m.k.device.MessageConnector : [f135f902] Device messages connection accepted 2021-09-20 18:00:13.069 ERROR [pool-1-thread-799] r.m.k.device.DeviceConnector : [f135f902] Unable to proceed, closing ru.mecotrade.kidtracker.exception.KidTrackerParseException: Leading symbol '[' not found in message "�AQSH+���~��|���C�� $$Z|��T�%�U�|aH� �" at ru.mecotrade.kidtracker.device.MessageConnector.process(MessageConnector.java:66) at ru.mecotrade.kidtracker.device.DeviceConnector.run(DeviceConnector.java:67) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)
Sorry I can't give more detailed information but I don't know too much about spring, java, etc. environment.

Platform data:

Ubuntu 21.04 (Linux 5.11.0-1015-raspi aarch64)
Docker version 20.10.7, build 20.10.7-0ubuntu1~21.04.1
docker-compose version 1.25.0, build unknown

Thanks in advance,

Hi @ferrebam ,
Thank you for reporting this issue! I have see two potential problems:

1. The no interaction problem might be related with a 3d party libraries I'm using, namely the Leaflet which is responsible for frawing the map. I also experience the very same problem, especially when log in from my phone. In my case it is sporadic: from other device, or after cleaning the cache or something I usually start seeing the map. BTW, did you allowed the webapp to use you geolocation? If not, it alows might entail such a behavior.
2. The server side is using a specific communication protocol, which is implemented in such baby smart watch as Q50, Q90 etc. Other models might use another protocol or version of protocol, which is not compatible with the server. Please let me know which model of watches you are binding to the server. Also, since the port is accessible from the Internet, any scammer could scan it. It might happen that the exception you have observed is not related to your watch, just an alien package trying to scan you server.

Hi @mecotrade ,

Thanks for your quickly response!

Today i was try to capture all trace from container boot to user input credentials, this is the result:

I see an error in boot process without user actions:

**WebSocketSession[0 current WS(0)-HttpStream(0)-HttpPoll(0), 0 total, 0 closed abnormally (0 connect failure, 0 send limit, 0 transport error)],**

After the startup process, I have connected through the portal but it shows the same screen that I sent yesterday, with no option to interact with the buttons or the map.
The log file only shows the user's connection, no other data:

2021-09-21 21:06:11.973 INFO [https-jsse-nio-8003-exec-1] o.a.c.c.C.[.[localhost].[/] : Initializing Spring DispatcherServlet 'dispatcherServlet' 2021-09-21 21:06:11.975 INFO [https-jsse-nio-8003-exec-1] o.s.w.s.DispatcherServlet : Initializing Servlet 'dispatcherServlet' 2021-09-21 21:06:11.985 INFO [https-jsse-nio-8003-exec-1] o.s.w.s.DispatcherServlet : Completed initialization in 8 ms 2021-09-21 21:06:27.749 INFO [https-jsse-nio-8003-exec-6] r.m.k.s.UserSessionListener : User successfully authenticated: UserInfo(id=1, timestamp=2021-09-09 18:17:58.104, createdBy=null, username=admin, name=Admin, phone=null, admin=true)

As for the device, I could see that the requests are from the watch that I tried to pair, the good news is that the sms worked and I was able to pass the parameters but it seems that it is not compatible with the server.
I don't know what version or gps system it uses internally, I know only the watch brand, https://www.savefamilygps.com/.
I have tried to get the current configuration by sending the command "pw,13456,ts#" getting the following:

ver:G72SC_ZMD_DF34_V1_HW_0.2_2019.08.15_09.16.01;
ID:0903379569;
imei:869609XXXXXXXX;

sos3:;
profile:1;
upload:60S;
bat level:100;
language:4;
zone:2.00;
GPS:NO(0);
NET:NO(100);

This is all I have been able to get.

Thank you very much

I can confirm same problem with not functional web frontend and no error in logs in:

• Play with Docker sandbox
• Docker Desktop on Windows
• docker engine on Raspberry Pi running debian

Same problem here, although I only face the issue in Browsers based on Chrome. In Firefox everything works.
Chrome doesn't even ask for Location permissions. Even if I allow them manually it doesn't work.

Edit: Nevermind. I've changed nothing and it doesn't work in Firefox anymore
