SLP Posted January 30, 2023 Posted January 30, 2023 Hi. I had a generalized internet outage (wifi, but also cell access ) recently, during which I discovered that UD Mobile was unable to log on. It could not resolve the URL name of my local ISY, and I got an error. Is there a best-practices or work around to allow the use of UD Mobile during generalized internet outages, i.e. like plugging in local IP vs. symbolic URL name etc ? Thank you in advance.

Hi @SLP, Results may vary depending on OS/Device and where the internet outage occurred. If Mobile internet (5G/etc.) is down but WiFi is not then UD Mobile's local connection settings will allow local access. If Portal is down but WiFi has internet then UD Mobile's local connection settings will allow local access. If WiFi does not have internet access then it is dependent on your mobile operating system. Most Android devices can join WiFi networks without internet access as long as user accepts a popup prompt allowing the connection. Android devices will also route network traffic to the WiFi network. iOS devices may be able to join WiFi networks without internet access but iOS will not route traffic to this network. There are a few ways to force this behavior programmatically. However forcing this behavior causes other issues such as preventing iOS from routing to mobile network when the WiFi network connection is poor, and will not work for VPN. Some apple devices such as WiFi only iPads, do not route any traffic to WiFi connections without internet. https://wiki.universal-devices.com/index.php?title=UD_Mobile#Local_Connections_and_Local_VP
