Would you mind to try reset the miner by holding any of these button reset/IP report button I don't know what exactly ebang 9.2 looks like but try to check if there are two buttons IP/reset button and hold it for 15 or 20 seconds then release if the miner restarts automatically it a success but if not manually replug it from the power source.
Then setup your pool again and test.
Would you mind also tell us if what pool do you mine?
Or I think contact Ebang support they have skype chat support here check these
