Quick Answer
When a website will not load, the problem can be DNS, SSL, redirects, hosting, firewall rules, or the page itself. Check each layer in order so you do not chase the wrong issue.
Step-by-Step
- Check whether the website is reachable over HTTPS and HTTP.
- Look up DNS records and confirm the domain points where you expect.
- Check SSL certificate validity, hostname coverage, and expiration.
- Inspect redirects and HTTP status codes for loops or blocked pages.
- Test from another network or device if the problem appears local.
Recommended Workflow
Open the most relevant calculator or utility first, enter a realistic starting point, then use the supporting tools to check assumptions, clean inputs, or prepare the final output.
FAQs
Should I check DNS or SSL first?
Start with reachability, then DNS, then SSL and redirects. That order usually finds the broken layer faster.
Can DNS changes take time?
Yes. Propagation and resolver caching can make records appear updated in one place and old in another.
Why does HTTPS fail while HTTP works?
The certificate may be expired, missing the hostname, misconfigured, or blocked by a proxy or firewall.
