As mentioned by @junjuew I accessed the training webpage from my phone as well but there is still no camera preview and the training just doesn't start. What can be the possible reason for this? Also I have enabled chrome to accept self-signed certificates. And I have tried clicking the link to accept the certificate as well. (Screenshots attached)
Regarding #1 @teiszler I tried accessing again and it says the site cannot provide a secure connection and an invalid response is being sent (ERR_SSL_PROTOCOL_ERROR)
Apologies for too many questions and issues but I am relatively new at this and want to be entirely clear about the project. Thank you in advance.
