Two different methods give two different answers for the Hubble Constant, and they aren't within the error bars.

The crux of it all is the Hubble Constant, a very important parameter that expresses the expansion rate of the Universe today. It is possible to measure this in multiple ways. An important one is by collecting the distance and recession velocity of many galaxies in the nearby universe. You can also obtain that from the CMB. There are other methods, but these two are the ones for which we have the highest precision, and there is a big problem. They produce two different numbers!

I would speculate that the Hubble formula is wrong. That's why they are getting two different answers. It's close, just as Newton was close with his laws of motion. But it's missing something. I have no idea what (or I'd publish and be up for a Nobel).

Physics is phun! :-)
