Can not resolve url due to multiple Trying 8.8.8.8:443...

[hungthele]

I am having issues with the https client multiple Trying to connect to 8.8.8.8:443...
May be the reason is Didn't find Session ID in cache for host HTTPS://dns.google:443
I'm not sure the root cause.
Log output below.

Any ideas? Please help me to find out the reason
