When you land on log5-applog-hl.novelfm.com, you get a 404 error and nothing else. That alone should stop you from doing anything here. The site has no working pages, no owner information, and an invalid SSL certificate. Even the domain's registration details are invisible — the WHOIS database returns no match, which is extremely unusual for any legitimate website.
A typical functioning website, even a small personal blog, would have at least an about page, a way to contact the owner, and a valid HTTPS connection. This subdomain has none of that. The fact that it's hosted on a mix of Chinese and US networks doesn't help, but the bigger problem is that it simply doesn't work as a website.
If you came across this domain wondering if it's a scam or fake, the honest answer is that it's not even a real site to begin with. There's nothing here to trust or distrust — it's a dead end. The safest move is to ignore it and move on to a site that actually has content, identity, and security.
