Hi @oneironautics, welcome to the forum 
Thanks for the details - I’ve passed them onto the team.
Given the GUI log it seems like Ping Viewer was waiting for responses that weren’t arriving, so it’s unlikely to be an issue with Ping Viewer. It’s unclear whether there’s
- a network issue stopping communication in one or both directions with BlueOS (although that should be noticeable with other communications also failing, like the telemetry and/or video stream)
- an issue with the bridge in BlueOS failing to correctly transfer information between Ping Viewer and the UDP connection to the topside IP
- an issue with the Ping360, where it for some reason stops responding (e.g. perhaps it crashes due to overheating, underpowering, or a firmware bug or something)
