Hi @Raj -  
The title of your post mentions BlueOS Factory version- are you running this or 1.3? Updating to 1.3.1 may help your issue - you can delete all unused versions, and update the bootstrap as well… Please share the results of a [network test](https://blueos.cloud/docs/latest/usage/advanced/#network-test) to ensure your connection quality is sufficient!
