Other comments in this topic already give a pretty good explanation of the situation, but I can also add some more details.
We recently updated the v2 Console to make it less confusing. Instead of showing incorrect information or empty pages, the Console now tries to hide parts of the user interface that rely on the “NOC” component when this “NOC” component isn’t available. Gateway status and live gateway traffic are the main features for which data is provided by the “NOC” component.
The problem here is that the “NOC” component is having issues. This is unfortunately something that happens more often. We made a lot of crucial mistakes when we initially designed the architecture of the NOC. As a result of these wrong architecture decisions, we’ve had a lot of difficulty scaling the NOC as The Things Network grew. We’ve had to disable some functionality (such as event history, searching for events, events from applications and end devices) to prevent it from crashing completely. Suffice to say, the NOC is always having a hard time, and it’s barely working most of the time.
In the meantime, the core team is now spending all its time on The Things Stack (v3), we’re not going to fix v2 issues anymore. The core team still does its best to resolve downtime of critical components in v2 deployments. Critical components are the components that are required for routing LoRaWAN traffic between Gateways and Applications. The “NOC” component is not considered critical, so we’re not going to spend a lot of time figuring out what’s wrong. Sometimes switching some things off and on again helps, but that’s all we’re going to do.
I would indeed like to take this opportunity to push you guys to The Things Stack (v3). Anyone who’s just getting started and doesn’t have working applications or end devices, and still relies on live gateway traffic, should really be using The Things Stack (v3). Anyone with working applications and end devices can use the data view of their application or end devices. But you should still migrate those to The Things Stack (v3) as soon as you can.
