How to Fix Proxy SSL & "Connection Not Private" Errors

Resolve the most common HTTPS issues quickly and safely.

First: Do NOT Ignore This Warning

A "Connection Not Private" or SSL warning can indicate that your secure connection is being intercepted or misconfigured. Do not click "Proceed" unless you fully trust the environment.

Check System Time

Incorrect system clocks break certificate validation. Sync time and retry.

Clear HSTS/SSL State

Old entries can force errors. Clear HSTS/SSL caches in your browser.

Use HTTPS URLs

Ensure you use https:// everywhere. Mixed content can trigger warnings.

Learn the Basics

Understand how encryption works to avoid pitfalls.

What Is an SSL Certificate? (The Internet's Digital Passport)

An SSL/TLS certificate works like a digital passport: it helps your browser verify a site's identity and establishes an encrypted channel so others can't read your data in transit.

Why Your Proxy Is Causing This Security Error

The #1 Reason: Encryption Is Being Broken

Some low‑quality proxies attempt to intercept HTTPS (a man‑in‑the‑middle), decrypt it, then re‑encrypt. This breaks the trust chain, so browsers raise a warning.

Other Causes: Outdated Protocols / Misconfig

Old TLS versions, weak ciphers, or incorrect proxy/browser settings can also trigger SSL errors.

The Safe Solution: A Proxy That Respects Your Secure Connection

Professional services never break end‑to‑end encryption. Unblockium uses modern CONNECT tunneling to keep your browser‑to‑site channel intact—we transport data, never peek at it.
