Restart solved the issue! But I think there is something that can be improved on the client to avoid restarting the client.

This is happening again and again... and the restart does not always solve the issue.

andreclaro commented 2 weeks ago

we are using the following bootnodes:

andreclaro commented 2 weeks ago

Do you have new or more bootnodes for testnet?

andreclaro commented 2 weeks ago

Our node is still unable to find peers...

andreclaro commented 2 weeks ago

The node was able to recovered by itself.

Anyway, support asked me to try to change sync-mode from FAST to SNAP and "If it works, I believe the issue was that your node already had some blockchain data stored locally, which prevented FAST sync from being enabled — it fell back to full sync. You can either sync using SNAP or clear your local blockchain data then restart your node using FAST. " - I did not try this. I will give it a try if the issue happens again.
