Hello @Tolga_Kaprol, we have identified a critical bug in OpenVidu with the symptoms you describe.
It is really hard for us to reproduce and to identify the root cause. Please can you help us to get more information about it? Can you take a look to github issue and test with a beta version we have just published?
@lihuapeng your problem seems very different. Can you give us access to the doc with OpenVidu logs so we can investigate?
Regards
