Security Certificate Misconfiguration

[Alpan]

I have been having a strange problem for a while now and am not sure if it's the site itself or my end only. This is what it says:

"The identity of this website is not verified. Server's security is not trusted"

"Your connection to this site is not private, attackers might be trying to steal your information from forum.paradoxplaza.com"

How do I fix this problem?

Try flushing your DNS cache and clearing your browser history.

I have been having this problem on mobile, I have noticed that on pc it occasionally says certain parts of the page are not secure. It is very strange because this occurs sometimes and other times it doesen't.
