Mining issue after 1.7 update

After 1.7 update, block sync works fine, but it is not mining.
Is there anything I should check?

Check that your /peers endpoint is healthy. Have a decent amount of peers, consider increasing the minimum_peers parameter. Enable -vv verbose logs and keep an eye on publishing and gossip activity. If anything of the above goes wrong, restart your node. Double check that your node has a valid chain head and that a valid 1.7 transaction processor is connected. Look for a message like “transaction processor 1.7 connected”. If it disconnects, you will see a hex connection_id disconnected message but you wont be able to tell if its a peer or the tp easily. Also keep an eye on publisher’s logs. A healthy node should log a few lines everytime it claims a block.
