How to Fix the “Your Connection Is Not Private” Error in HubSpot

Seeing a “Your connection is not private” warning on a HubSpot page or any website can be alarming, especially when you are trying to log in, manage content, or access key tools. This guide walks you through practical steps to fix the error and understand what is happening behind the scenes.

While the screenshots and explanations in the original guide focus on Chrome, the same principles apply across other browsers like Safari, Firefox, and Edge.

What the Error Means for HubSpot Users

When you load a page, your browser checks whether the connection between your device and the website server is secure. If something looks wrong, it can trigger a privacy warning, including on HubSpot-hosted pages.

The “Your connection is not private” message usually signals an SSL or HTTPS issue. SSL (Secure Sockets Layer) encrypts data between your browser and the website so that sensitive data cannot be easily intercepted.

If the browser cannot validate that encryption, it shows one of several possible messages:

  • Your connection is not private
  • Attackers might be trying to steal your information
  • Your connection is not secure
  • This site is not secure

In a business context, this can impact form submissions, payments, and logins on HubSpot and other platforms.

Common Error Codes You May See

When you get a connection warning on a HubSpot site or any secure site, the browser may include an error code that gives more detail. Examples include:

  • NET::ERR_CERT_AUTHORITY_INVALID
  • NET::ERR_CERT_COMMON_NAME_INVALID
  • NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM
  • ERR_CERT_DATE_INVALID
  • SSL_CERTIFICATE_ERROR
  • DLG_FLAGS_SEC_CERT_CN_INVALID

These all point to some form of SSL certificate or connection validation problem. The steps below help you diagnose and resolve them.

Quick Safety Check Before You Proceed

Before troubleshooting a HubSpot page or any website, confirm that you trust the site:

  • Make sure you typed the URL correctly.
  • Avoid entering passwords or payment data until the warning is resolved.
  • If you followed a suspicious link from email or social media, close the tab and navigate directly to the known domain.

If you are confident the site is legitimate, continue with the steps below.

Step 1: Reload the HubSpot Page

Sometimes the connection error is temporary and can be cleared with a refresh.

  1. Click the refresh icon in your browser, or press Ctrl + R (Windows) or Cmd + R (Mac).
  2. If the error disappears, it was likely a one-time network hiccup or a partial SSL handshake failure.

If it persists on a HubSpot landing page or dashboard, move on to the next steps.

Step 2: Check Your Internet Connection

An unstable or intercepted connection can cause security warnings, even on trusted platforms like HubSpot.

  • Disconnect from public Wi-Fi if possible.
  • Toggle Airplane Mode on and off, or restart your router.
  • Try another network, such as a mobile hotspot, to see if the error is network-specific.

If HubSpot loads correctly on a different network, the original connection may have filtering or interception issues.

Step 3: Verify the System Date and Time

SSL certificates are valid only within a specific date range. If your device clock is wrong, your browser may think the certificate on a HubSpot page is expired or not yet valid.

  1. Open your device settings.
  2. Check the Date & Time settings.
  3. Enable automatic time and time zone synchronization if available.
  4. Restart the browser and revisit the site.

Correcting the clock often resolves ERR_CERT_DATE_INVALID and similar errors.

Step 4: Use Incognito or Private Mode

Browser extensions or cached data can interfere with secure connections to HubSpot tools or portals.

  1. Open an incognito or private browsing window.
  2. Visit the same URL.

If the HubSpot page loads fine in private mode, the issue is likely caused by an extension or corrupted cache in your normal browser session.

Step 5: Clear Browser Cache and Cookies

Old or corrupted cache files may conflict with updated SSL certificates, including those used by HubSpot-hosted domains.

  1. Open your browser settings.
  2. Find Privacy or History.
  3. Clear cache and cookies for at least the last 7–30 days.
  4. Restart the browser and test the page again.

This step is especially useful if you only recently set up SSL or made domain changes.

Step 6: Disable Browser Extensions Temporarily

Security, VPN, or content-filtering extensions may block scripts or certificates and trigger warnings, even on trusted platforms like HubSpot.

  1. Disable all extensions.
  2. Reload the problem page.
  3. Re-enable extensions one by one to identify which one causes the issue.

Once identified, adjust that extension’s settings or stop using it on sensitive login or checkout pages.

Step 7: Check Antivirus or Firewall HTTPS Scanning

Some antivirus tools inspect HTTPS traffic and install their own local certificates. This can lead to certificate errors when visiting HubSpot or other secure platforms if the feature misbehaves.

  1. Open your antivirus or security suite.
  2. Look for HTTPS scanning, SSL scanning, or similar settings.
  3. Temporarily disable this feature.
  4. Restart your browser and revisit the site.

If the warning disappears, update or reconfigure the antivirus and consider contacting the vendor for best-practice settings.

Step 8: Try a Different Browser

If the connection error appears only in one browser but not another, the cause may be specific to that browser’s profile.

  • Open another browser and log into your HubSpot account or test the affected URL.
  • If the problem is isolated, consider resetting or reinstalling the problematic browser.

This test helps you determine whether you are dealing with a device-wide issue or a browser-specific one.

Step 9: Inspect the SSL Certificate Details

When you own or manage the website, including a HubSpot-connected domain, inspect the certificate to ensure it is valid and correctly configured.

  1. Click the padlock icon in the browser address bar (if available).
  2. View the certificate details.
  3. Check:
  • The domain name matches the site you are visiting.
  • The certificate has not expired.
  • The issuing certificate authority is trusted.

If the certificate is missing, expired, or mismatched, you need to correct it at your host, DNS, or SSL provider.

Step 10: HubSpot-Specific SSL Considerations

When your website or landing pages are hosted or connected through HubSpot, SSL is usually managed automatically, but some misconfigurations can still occur.

  • Confirm that your custom domain is correctly connected in your HubSpot domain settings.
  • Allow time for SSL provisioning after adding or changing a domain.
  • Ensure DNS records (such as CNAME) match the instructions in your HubSpot account.

When You Should Not Bypass the Warning

You can sometimes click “Advanced” and proceed to the page anyway, but this is risky on unknown sites. In general, do not bypass the error if:

  • You do not recognize the domain.
  • The page asks for personal, financial, or login data.
  • The site was reached via a suspicious email or pop-up link.

For business-critical systems, including HubSpot, always confirm the URL and validate that SSL is correctly set up before submitting sensitive information.

HubSpot Troubleshooting vs. Broader Website Strategy

Fixing the “Your connection is not private” error is only one part of maintaining a secure and high-converting digital experience. Beyond resolving SSL issues, you should ensure fast loading times, strong technical SEO, and consistent branding across your HubSpot content and other platforms.
