Scheduler works fine but some articles do not show as published until the cache is cleared [#3202777]

I have a scheduler which imports articles at a specific time. I can see the content is getting scheduled properly using the scheduled tab but I cannot see the published content. Every morning I need to manually clear the cache to see the scheduled content published otherwise all node goes to 403. Any Idea on this? I tried clearing node tag cache on Scheduler publish event but still didn't worked. Any idea?

Also, I noticed when clearing memcache resolves the issue. I tried to clear the node:nid cache tag on schedule publish event but still didn't worked.
Any idea?

 public function onSchedulePublish(SchedulerEvent $event) {
  /** @var \Drupal\node\Entity\Node $node */
  $node = $event->getNode();
  Cache::invalidateTags($node->getCacheTagsToInvalidate());
  $message = "Node Published and invalidate the cache tags" . $node->id();
  $this->logger->notice($message);
 }

I used CTC clear cache tag module to see which all cache tag can help to clear the necessary cache.
I tried node:nid and node_values and it worked.

Hi Dinesh,
In principle Scheduler works properly, there are no cache problems. So this is a normal support request, not a critical bug. There must be some other module or set-up on your site which is doing things with caching. It sounds like you have some ideas for your investigations.

I fixed the issue by using the below code

	 * Subscriber Callback for the event.
	 * @param SchedulerEvent $event
	 */
	public function onSchedulePublish(SchedulerEvent $event) {
		/** @var \Drupal\node\Entity\Node $node */
		$node = $event->getNode();
		$tags = ['node:' . $node->id(), 'node_values'];
		Cache::invalidateTags($tags);
		$message = "Node Published and invalidate the cache tags" . $node->id();
		$this->logger->notice($message);
	}
