Hello, my hikvision surveillance camera model DS-2CD2047G1-L worked perfectly via SMB / CIFS with the firmware version that came from the factory 5.5.84_19082 after the update to version 5.5.87_200103 SMB / CIFS no longer works can no longer connect on the hard disk why? I reset the camera to factory settings after the update and in vain SMB / CIFS no longer works
