MinerOS has got my rig fans spinning, but no GPU activity or coins being mined

I am following this guide 3分钟搞定挖矿系统,开挖Pmeer之minerOS新司机指南 and have successfully set up the template. The minerOS loads up, but I cannot enter my mos password it is saying it is incorrect. The guide says you do not need to do anything on the rig anyway. The fans are spinning loudly but the coins are not coming in. What do I have to do? Thank you

Getting connection refused. Can someone help me with setting up ports?
