Yup my wallet is like yours on the self pool. Still fails to join the real pool, even after hours. Either there's something wrong with the plotnft command (it has a slightly different set of arguments than the self pool), or is it possible the url isn't working correctly right now?
Either way I'll just keep self mining until I figure this out. I'm generally pretty tech literate, but this Chia is streaching my knowledge a bit.
