Why do I run into an error message when trying to use datascopeSelect()?

When I try to run the following command, then it fails with an error where it has worked fine a while ago:

>> c = datascopeSelect(username,password)

Error using matlab.net.http.RequestMessage/sendOneRequest (line 1364)
Secure connection to "https://selectapi.datascope.refinitiv.com/RestApi/v1/Authentication/RequestToken" not established because "Recv failure: Connection was reset".
Check your system certificates for expired, missing, or invalid certificates.

Some of the underlying REST API URLs have changed for datascope Select which might now cause this error message. As a workaround you can try to pass the actual URL instead of relying on the default URL in the datascopeSelect() function:

>> c = datascopeSelect("username","password",200,"https://selectapi.datascope.lseg.com/RestApi/v1/Authentication/RequestToken")
