I had a problem where a Teams for Rooms device, on Android was going offline all the time which got me curious as to why to from the Team Admin centre navigate to Teams Devices > Teams Rooms on Android as below:
Then locate your device that is not working or going Offline the choose the "History" option then from here you need to find the date that the device went "Offline" as you can see below in the greenbox:
Then we want to download this file, this will be the full diagnostic file for the device itself which should in turn tell you if there are any issues with the room, but there is lots of data to navigate though depending on the data that you download and the type of diagnostics.

This is very accurate to what you observed locally in the meeting room, so that summary will also have the detailed information shown for further diagnostics, let take a look at this now below.
Detailed Error Extraction
You can see lots of errors (in bold) linked to not being on the network which is what would cause the issue experienced on the day.
- Exception: IBaseService Service is not ready
- Exception() :: mIsIgnoreException is [true] :: skipped
- Exception: Service interface was null in service manager, for class=[com.logitech.service.modeservice.IModeService]
- Exception: Failed to prepare /sdcard/Android/data/com.logitech.service.policy/files

Then it tries to talk to the internet without any Internet connection and fails to talk on SSL:
- Exception: Read error: ssl=0x7d7b726f08: I/O error during system call, Connection reset by peer
- Exception: Read error: ssl\u003d0x7d7b726f08: I/O error during system call, Connection reset by peer\n\tat com.android.org.conscrypt.NativeCrypto.SSL_read(Native Method)\n\tat com.android.org.conscrypt.NativeSsl.read(NativeSsl.java:411)\n\tat com.android.org.conscrypt.ConscryptFileDescriptorSocket$SSLInputStream.read(ConscryptFileDescriptorSocket.java:549)\n\tat okio.InputStreamSource.read(JvmOkio.kt:93)\n\tat okio.AsyncTimeout$source$1.read(AsyncTimeout.kt:153)\n\tat okio.RealBufferedSource.request(RealBufferedSource.kt:209)\n\tat okio.RealBufferedSource.require(RealBufferedSource.kt:202)\n\tat okhttp3.internal.http2.Http2Reader.nextFrame(Http2Reader.kt:90)\n\tat okhttp3.internal.http2.Http2Connection$ReaderRunnable.invoke(Http2Connection.kt:625)\n\tat okhttp3.internal.http2.Http2Connection$ReaderRunnable.invoke(Http2Connection.kt:616)\n\tat okhttp3.internal.concurrent.TaskQueue$execute$1.runOnce(TaskQueue.kt:106)\n\tat okhttp3.internal.concurrent.TaskRunner.runTask(TaskRunner.kt:122)\n\tat okhttp3.internal.concurrent.TaskRunner.access$runTask
