Hi, it appears that my problem is different and it got resolved after I restarted the OS. Restarting the core alone doesn’t solve the problem.
Going through the log files in detailed again and I noticed there was instance my camera lost connection and I suspect there either my router got restarted itself or my internet connection has restarted and causing the HA socket connection screw up.
Anyway, my HA is now back online. Thanks for the comment and reply.
