This issue is only reproducible on certain networks, what I do to solved it is literally moving to another place. Certain IP’s im not sure why, block all network requests. If I find another network that blocks network I will give you more information. This also happens 100% of the time doing this: 1. Im connected to a network. 2. I move to another place, with another network. 3. I reload the app by doing kepler device launch-app, then I see ERR\_NETWORK request failed. Sometimes this gets fixed by restarting the simulator but sometimes not. ---

Hey @Sofia_Lozada_Tenorio Thanks for the details. This seems like an network issue more than the OS issue. However, we would need the logs from your device to understand what happened here better. Kindly share the logs captured while this issue is happening. Warm regards, Ivy ---
