I see that you have 4% stale shares poolside even though your settings look good to avoid stale shares. You have a high ping to the server 155ms

Try to change the server to get better ping

asia2.ethermine.org
asia1.ethermine.org
eu1.ethermine.org
us1.ethermine.org
us2.ethermine.org

Or change to a pool that pay for stale shares.
