How to reconnect to a stream automatically - Web SDK 2.0 - EN - Flashphoner Documentation

docs.flashphoner.com docs.flashphoner.com

This doc is not applied to Room API directly.

Try to re-Join instead or re-publish stream to the room

Code: 
joinRoom();
or

Code: 
publishLocalMedia(room);

As you can see from the code attached above, I rejoined the room and published the stream.
A problem occurs when the Samsung Galaxy S10 5g phone is used in wifi and forced to change to lte.
Once the problem occurs, the problem persists after pressing the refresh button.
If you completely close the mobile browser and access it from lte again, there is no problem.

The weird thing is that the iphone 11pro and galaxy s20, galaxy s10a are fine..

When I check the server log, it is as shown below.

As we wrote above, reconnection example can be applied to playback only. Also, the case of connection closing is not described in the example.
Please implement playback reconnection as described, and try to reproduce the issue on the phone.
In the conference case, you should check:
- if just one participants stream playback failed, but session is not closed, you should just re-play the participants stream. this can be done automatically when participant is re-joined
- if local stream publishing failed, or session is closed, you should reestablish session: connection.disconnect(), Flashphoner.roomApi.connect then joinRoom

I understand that the example doesn't fit the conferece example.
I tried to find the code for the conference example, but couldn't find it.
So it was arbitrarily modified..

Currently, I added a log in the attached code and checked it.

- Wifi
Flashphoner.roomApi.connect > joinRoom > Local stream published ( SUCCESS )
- Lte ( forced change )
Local stream failed > Flashphoner.roomApi.connect > joinRoom > Local stream failed ( FAILED - retry 1 )
( At this time, session_status was established, so connection.disconnect() was not performed. )
connection.disconnect() > Flashphoner.roomApi.connect > joinRoom > Local stream failed ( FAILED - retry 2 )
connection.disconnect() > Flashphoner.roomApi.connect > joinRoom > Local stream failed ( FAILED - retry 3 )
...
The problem persists even when I refresh the page.

Isn't this the way you described it?
I'm only looking at the publish side.

If there was a problem with the code, shouldn't it work on other phones?
Have I ever misunderstood?

When you forcefully change network type, you must create a new sessoin. So, do the session reconnection always in your code when local publishing is failed.
