Why do I see the error: TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https
|Knowledge Article Number||000232847|
|Description||To help customers test and prepare for the TLS 1.0 deprecation , Salesforce has provided customers with the Critical Update feature Require TLS 1.1 or higher for HTTPS.
What does the update do?
This critical update, when activated, disables TLS 1.0 in the following communication channels with the org:
This feature can be used by customers to disable TLS 1.0 ahead of Salesforce's schedule. Customers can use this for testing how absence of TLS 1.0 affects their connections or they can just use it to switch over to the more secure TLS 1.1 and TLS 1.2.
The following steps can be followed to disable this feature:
- Navigate to Setup
- In the Quick Find bar, type in Critical Updates
- Select Critical Updates
- Locate the Require TLS 1.1 or higher for HTTPS connections under the Update Name column
- Click on Deactivate.
This feature comes deactivated by default. If customers find it activated already, it might have been done unintentionally by an administrator. The respective entry for that change can be found in the Setup Audit Trail.
