callout error :TLSv1

System.CalloutException: Server chose TLSv1, but that protocol version is not enabled or not supported by the client.

may i know how i can be acheived in developer edition ??????
Environment :  developer edition
I am using callout to pull the data from api to Salsesforce. It was working bfore.  Today I ran the apex callout and got the following error
System.CalloutException: Server chose TLSv1, but that protocol version is not enabled or not supported by the client
Then I checked Internet about this error and came to know that salesforce disabled TLS 1.0. I also got some information TLS 1.0 Disablement Critical Update Console (CRUC) Setting. But unfortunately am not able to see that Require TLS 1.1 or higher for HTTPS connections in CRUC.
