Why does my HTC U11 keep rebooting after installing Oreo 8?

[Android Central Question]

I have download the Oreo and installed on my HTC U11 two weeks ago. Since then, I have been having problems with my phone rebooting from time to time. Sometimes about 6 times in a day. May I know if this is an update problem?
