Hi @Balaji_Ramachari ----- Thank you for the report and sharing your feedback with us. Both are very appreciated!
Moving forward, I agree with @Rugby’s suggestion(s) and would recommend confirming that information as those are good starting points in addressing this behavior (i.e Wifi is on and all devices are on the same subnet). Furthermore, please verify that you have also added RAATServer to the Windows firewall exceptions list.
Lastly, I had another user report a similar issue with a remote device and the was resolved by adjusting the settings in Avast.
Thanks for the feedback. I checked the Raat server exclusions again on Windows Firewall exclusions. There were two of them checked all both “Private” & “Public” and restarted my Android phone as well. It worked !! Delighted with the sound through the phone
