Network connection error

We are getting the following error in our lab network.

No beacons for given tag values. Make sure you’ve entered tag names correctly, your app has network connection available (at least once), and tags are correctly assigned to your beacons in Estimote Cloud.

Which is the IP we have to enable to get the access to Estimote.

Hi @nandhu
you should be good to go if you whitelist the domain — that’s where all our API requests hit.
Let us know if that helps!
