Hi @yatender_kumar,
It is most advisable that you do not use a self signed cert. You can obtain a valid cert for free from https://letsencrypt.org.
That said, you can uncomment:
;settings.clientConfig.verifySSL = false
in /opt/kaltura//app/configurations/admin.ini and:
;clientConfig.verifySSL = 0
in /opt/kaltura/app/configurations/batch/batch.ini
then reload Apache which should make the self signed cert work.
However, you are still likely to have issues with KMC when using certain browsers.
Bottom line, best get a valid cert from https://letsencrypt.org.
It’s a fairly simple process that should take more than 5 minutes or so and you can set up auto renewal as well.
