Our NodeJS application, running in UBUNTU uses MediaSoup for video/audio transmitting. It is working when we are not using any SSL certificate for our website. But after SSL certificate is enabled, MediaSoup stops transmitting.
Mediasoup doesn’t require any certificates to be specified.
It might use some, there are options for that, but unless you understand why your use case requires them (which, admittedly, is not the case here), just don’t bother.
SSL certificates on website have nothing to do with mediasoup itself.
