Uncaught exception 'KalturaClientException' with message 'failed to unserialize server result

Hi Jess,

I wonder if you could help me with your advice. I have the error message below.
My SSL settings: one is set to verify and another to not verify.
I got new SSL crt & added chain file.
I did run kaltura-front-config.sh .
I have the HTTP 403 error. The website declined to show this webpage.
Thank you for your time and effort.
Dmitri
