What Causes Error 1027c?

Error 1027c most commonly occurs due to the following issues:

  • Invalid or expired SSL certificate on the website
  • Problems with the HTTPS/SSL configuration on the web server
  • Connectivity issues between the client and web server
  • Outdated cipher suites or protocols supported by the web server
  • Problems with the QUIC protocol settings in Chrome browser
  • Conflicts with antivirus or firewall software on the client computer

Essentially, this error stems from a failure to establish a secure encrypted connection between the website and your browser. Without a proper SSL/TLS handshake and encryption, the browser cannot securely retrieve the website content, leading to Error 1027c.

Step 1: Check SSL Certificates and HTTPS Configuration

The first step is to check whether the target website has a valid SSL certificate installed. The certificate establishes trust between the website and browsers, enabling encrypted HTTPS connections.

Verify the Website has a Valid Certificate

  • Try accessing the website URL with https:// in front (e.g. https://www.example.com). If you get a certificate warning, there is an issue with the SSL certificate.
  • Use an online SSL checker tool to validate the certificate. Tools like SSLShopper can identify expired, invalid, or misconfigured certs.
  • Check the certificate for the correct domain name. The domain should match what you entered in the browser.
  • Confirm the certificate is signed by a trusted Certificate Authority like Comodo, Symantec, GoDaddy, etc. Self-signed certificates will also trigger errors.

If you find any problems with the SSL certificate, notify the website owner. They will need to renew or reinstall a valid certificate to resolve Error 1027c.

Verify HTTPS and TLS Settings

Website owners should also verify the HTTPS and TLS configuration on the web server matches modern best practices:

  • Confirm the site is hosted on a web server like Apache or Nginx and has the HTTPS module enabled. The SSL certificate will not work without proper server-side support.
  • Check that the web server is configured with TLS 1.2 and TLS 1.3 enabled, and older SSL protocols disabled. This ensures support for the latest cipher suites that browsers require.
  • The server should support modern cipher suites like AES-256 and ECDHE for perfect forward secrecy. Weak ciphers like RC4 and SHA-1 may trigger connection errors.
  • Enable HTTP Strict Transport Security (HSTS) to enforce HTTPS connections on the website.

Work with your hosting provider to update insecure HTTPS configurations that can cause Error 1027c for visitors.

Step 2: Disable QUIC Protocol in Chrome

For Chrome users specifically, another common cause of Error 1027c is conflicts with the experimental QUIC protocol supported by Chrome.

QUIC is designed to speed up secure connections by reducing handshake latency. However, not all websites fully support it yet. To test if QUIC is the issue:

  1. Type chrome://flags/#enable-quic in the Chrome address bar and hit Enter.
  2. Find the Enable QUIC option and change the drop-down menu from Enabled to Disabled.
  3. Relaunch Chrome and try loading the website again.

Disabling QUIC support in Chrome may allow you to bypass Error 1027c for sites with limited QUIC compatibility.

Step 3: Whitelist Website in Antivirus and Firewall

Third-party security software like antivirus, VPNs, and firewalls can sometimes interfere with SSL encrypted connections, causing Error 1027c in browsers.

Try whitelisting the affected website in the settings of your antivirus, Windows Firewall, or any other network security software installed on your system. This allows traffic to that site to bypass security filtering that may be blocking the SSL connection.

To whitelist a website:

  1. Open your antivirus or firewall settings
  2. Navigate to the website filtering or whitelist section
  3. Add the problematic website URL to the allowed list
  4. Save changes and restart your computer

With the website whitelisted, reconnect to the site to see if Error 1027c persists. This simple fix resolves connections blocked by overzealous network security tools.

Step 4: Update Network Drivers and Verify Connectivity

Network connection issues between your computer and the website can also manifest as Error 1027c in some situations.

Try the following basic connectivity checks:

  • Make sure you have an active internet connection on your computer
  • Confirm you can reach other HTTPS websites without issues
  • Ping the problematic website domain from the command prompt to check for packet loss
  • Reset your network devices like router, modem, access points etc.
  • Update network adapter drivers on your computer to the latest available versions
  • Try accessing the website from a different network location, on different devices

If you can connect to other HTTPS sites but the target site fails, something is blocking connectivity specifically to that domain. Work with your ISP or network admin to troubleshoot potential firewall or routing issues.

Step 5: Flush DNS and Renew IP Address

Outdated DNS records and IP assignments can also prevent your computer from securely accessing the HTTPS website. Flushing stale DNS entries and renewing your IP address forces your system to freshly pull the site’s up-to-date endpoint:

On Windows:

  1. Open Command Prompt as Administrator
  2. Run the command ipconfig /flushdns to flush DNS cache
  3. Run ipconfig /registerdns to refresh DNS
  4. Run ipconfig /release and ipconfig /renew to renew IP address

On Mac:

  1. Open Terminal
  2. Run sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder to flush DNS
  3. Renew IP with sudo ipconfig set en0 BOOTP

Once your DNS and IP are refreshed, attempt to connect to the website again to see if Error 1027c is resolved.

Step 6: Clear Browser Cache

Clearing your browser cache helps eliminate stale content or broken entries that may disrupt secure website connections.

On Chrome, Firefox, Edge etc, open Settings, go to Privacy/History section, and choose to clear cache and cookies. Restart your browser and connect to the website again.

This wipes out any cached SSL data that could be triggering Error 1027c.

Step 7: Try an Alternative Browser

If the error persists across browser cache clears, try using a different browser like Firefox or Edge to access the same website.

See if the connection issue only appears on a certain browser. If Firefox loads the site fine, then there is likely a browser-specific settings conflict in Chrome. You can then reset Chrome to default settings or investigate further Chrome extensions that may cause problems.

Switching browsers helps isolate whether Error 1027c stems from general computer, network, or browser-related settings.

Advanced Troubleshooting Checks

For advanced users, you can also perform checks like:

  • Verifying cipher suites match between server and client using the SSL Labs Server Test
  • Testing site connectivity with utilities like OpenSSL and Wireshark to isolate blocking
  • Examining browser console logs for specific SSL errors like ERR_SSL_VERSION_OR_CIPHER_MISMATCH
  • Checking for problems with a CDN service if the site uses one to manage SSL
  • Testing from different physical locations to identify potential geographic network issues

However for most users, the simple solutions outlined earlier in the guide will resolve Error 1027c. Focus on updating certificates, browser settings, antivirus, DNS, and general network connectivity first before diving deeper.

Contact Website Support

If you have tried the various troubleshooting steps but Error 1027c still occurs, reach out directly to the website owner’s technical support team.

Provide details like exactly when the error occurs, what browser you use, and any error codes or log details. This information helps them investigate and fix SSL configuration or server issues blocking you from accessing the site.

Most site owners will be happy to resolve Error 1027c instances for their users as encrypted HTTPS connectivity is vital for both security and performance today.

Prevention

To avoid Error 1027c in the future when accessing websites:

  • Ensure browsers are updated to the latest available version
  • Periodically clear browser caches, cookies and history
  • Keep antivirus, firewalls, VPNs etc updated or whitelist trusted sites
  • Watch for certificate expiration dates on critical websites
  • Notify sites early if you encounter SSL connectivity problems

Proactively troubleshooting on both the client-side and server-side is key to avoiding frustrating and persistent Error 1027c situations that disrupt website use.

Conclusion

Error 1027c generally indicates an issue with establishing an encrypted HTTPS connection with a website. Invalid SSL certificates, Chrome’s QUIC protocol, security software conflicts, DNS problems, and general network connectivity glitches can all trigger this error.

Carefully going through certificate validation, browser, antivirus, DNS, and network troubleshooting steps will uncover the root cause in most cases. For sites you access frequently, take preventative measures like whitelisting, keeping software updated, clearing browser caches, and monitoring SSL expirations.

Paying attention to Error 1027c warnings and addressing them promptly ensures you have continuous secure access to your essential HTTPS-enabled websites and web applications.
