Golem Providers needs to restart to start receiving tasks again.

[cryptobench]

We've identified a bug where providers on the network doesn't seem to broadcast their offers to the rest of the network. The provider having issues has a fine online status on the network, but it's simply just not letting the network know about its proposals/offers.

How to identify "stuck/broken" nodes requiring a restart:

1. Fetch either all providers on the network via https://api.stats.golem.network/v2/network/online or fetch a specific node here https://api.stats.golem.network/v2/provider/node/0x964cffd7f02044e66d60f00c95adc122a7545309

2. Find your node in the list

3. Look for runtimes.vm.updated_at and verify if the last update is 2 hours ago or more. You can define this interval yourself and it can probably be lower but I haven't tested that.

On the stats page we verify online statuses of the nodes via yagna net find and that returns OK, so we keep the provider as online on the stats page, but we can verify through the API that some nodes haven't sent a new offer for multiple hours.

To easily identify a broken node, you can also browse the visuals on the stats page here which will mark providers with issues https://stats.golem.network/network/providers/online
