CC3220MOD: Socket error during OTA update

Part Number:CC3220MOD

Hey community,

During the OTA update process, the following error shows up, which makes the update fails. Any idea what's the cause of it ?

"Error accepting client connection, error -95"

Error -95 : "Operation not supported on transport endpoint"  (SL_ERROR_BSD_EOPNOTSUPP).

Thanks in advance !
