Error sending HTTP request to https://api.box.com:443/2.0/files/780321868959/content/

While i am retrieving data using box Rest-API's, getting an exception
(connection timed out: Error sending HTTP request to https://api.box.com:443/2.0/files/780321868959/content/) .
Scenario is that we have many operations performed on the files present in box account like getting folder contents ,deleting a file, copying a file in this particular application.
But this error occurs only for operation "Get File Content".We are using the rest api to perform this operation in our mule application.
I enclose this particular http call inside a "until_successfull" block which retires the connection until a success response is received,
so for every 10 files this issue is happening twice.
The issue is gets resolved after 1 or 2 retries(with 5000ms retry time gap) but that makes the application we developed time consuming

Error log:
ERROR 2021-02-25 13:50:07,599 [[abc-api].http.requester.Box_HTTP_Request_configuration.04 SelectorRunner] [processor: read-and-transform-data-from-file-flow/processors/2/route/0/processors/0/processors/1; event: 211eddf0-7742-11eb-8272-00059a3c7a00] org.mule.extension.http.internal.request.HttpRequester: Error sending HTTP request to https://api.box.com:443/2.0/files/780321868959/content/

We really appreciate you can let us know the exact cause of these exceptions , so we can handle these exceptions in proper manner.
