The ERR_SSL_OBSOLETE_VERSION error in Chrome means the website tried to connect with TLS 1.0 or TLS 1.1, old versions of the security protocol that protects HTTPS pages. Chrome shows an error for those versions, so the real fix is on the website’s server. Google’s SSLVersionMin policy notes say that suppressing the TLS 1.0/1.1 warning is no longer supported.
Quick Fixes to Try First
- Refresh the page and check if the error persists.
- Restart Chrome by closing and reopening the browser.
- Make sure Chrome is up to date. Our guide to updating Chrome covers every device.
- Try the site on another network. A work proxy or antivirus “HTTPS scanning” feature can change how the connection is made.
Understanding the TLS Version Requirements in Chrome
Chrome expects websites to support TLS 1.2 or higher. TLS 1.0 and 1.1 are considered insecure. Companies used to be able to hide the warning for these old versions with a Chrome policy. Google removed that option in 2021, and there is no setting or flag in Chrome that turns the old versions back on.
That means nothing in Chrome’s settings will fix this error on your side. If the site is one you need, contact the people who run it and tell them it needs TLS 1.2 or newer.
Check Your Chrome Version
- Select More (three dots) > Help > About Google Chrome, or enter
chrome://settings/helpin the address bar. - Chrome checks for an update and installs it. Select Relaunch when it appears.
Server-Side Fixes for TLS Version Errors
If you’re a website administrator, ensuring your server is configured for modern security protocols is essential. Here’s how you can update your server:
- Check your server’s current TLS configuration.
- Update your server software to support TLS 1.2 or higher. Google’s Chrome error help recommends TLS 1.3, while keeping TLS 1.2 available for older clients.
- Test your server using online tools like SSL Labs to ensure compliance.
Frequently Asked Questions
What does ERR_SSL_OBSOLETE_VERSION mean?
This error indicates that the website is using an outdated SSL/TLS protocol version that Chrome no longer accepts.
Can I ignore the ERR_SSL_OBSOLETE_VERSION error?
It’s not recommended. Unless your organization has set a policy that blocks it, Chrome may let you continue past the error, but the old protocol has known weaknesses, so anything you send to that site is less protected.
How do I update my server’s TLS version?
Contact your server administrator or hosting provider to update the server software to support TLS 1.2 or higher.
Can I turn old TLS versions back on in Chrome?
No. There is no Chrome setting or flag for it, and Google removed the policy option that hid the warning. Only the website can fix it.
How do I check my Chrome version?
