it looks you are an Apac based SE , will contact you to discuss this as am working on something similar in Techsupport
If it's working for a few days and then it stops, it doesn't look like a configuration problem (or at least not initially). Can you capture device logs through ADB and attach them here? There will probably be information of interest there that can help troubleshoot this.
Does the problem persist after a reboot?

yes it persist after a normal reboot. We need to do an enterprise reset or factory reset everytime.
