Hey lemlister! 👋
If you’re encountering an error related to TLS, it likely means your server doesn’t support TLSv1.2. Our system no longer supports TLSv1.0 or TLSv1.1 because these protocols are outdated and no longer secure. Let’s walk through what TLS is, why it matters, and what you need to do to resolve this issue.
What Is TLS?
Transport Layer Security (TLS) is a cryptographic protocol that ensures secure communication over the internet by encrypting data between servers and browsers. It’s essential for secure activities like:
Web browsing
E-commerce
Online banking
Email communication
The Evolution of TLS
TLS has improved significantly over the years:
TLS 1.0 (1999): Replaced SSL, addressing many vulnerabilities in earlier protocols.
TLS 1.1 (2006): Added extra security improvements.
TLS 1.2 (2008): The current standard, offering stronger encryption and better security.
TLS 1.3 (2018): Enhanced encryption and improved performance.
Why Are TLSv1.0 and TLSv1.1 No Longer Supported?
These older versions have known vulnerabilities, such as weak cryptographic algorithms, making them prone to attacks like data interception and decryption.
To enhance security, many organizations, including us, have discontinued support for TLSv1.0 and TLSv1.1.
What You Can Do
Upgrade Your System
Contact your IT department to ensure your server supports TLSv1.2 or higher.
Switch to a Reputable Provider
Consider transitioning to trusted providers like G Suite, Outlook, or Office 365, which support modern security protocols.
Microsoft’s TLS Update
As of August 1, 2023, Microsoft no longer supports TLSv1.0 and TLSv1.1 in future Windows versions. Here’s what you need to know:
Microsoft has recommended upgrading to TLSv1.2 or higher since 2020.
Systems relying on older TLS versions must transition to avoid compatibility and security issues.
Why Upgrading Matters
Cyber threats are becoming more sophisticated. Using TLSv1.2 or higher ensures:
Protection against attacks.
Compatibility with modern systems.
Uninterrupted service across platforms.
Stay Secure with TLSv1.2
If you’re still relying on older TLS versions, now’s the time to upgrade. Transitioning to TLSv1.2 is straightforward for most modern web servers, and it will future-proof your systems against security vulnerabilities and compatibility issues.
