Russian lost Kherson, a city with a population of 280,000 (pre-war 2020). It was the only administration center of an Oblast (sort of like a U. S. state) that Russia captured in 2022. It was abandoned by the Russians within a few days of the U. S. elections in November (don't want to hurt the Pro-Trump candidates). So they needed something to offset the loss of that city, for the Russian public.
The Russians believed they could take Bakhmut, a town of 70,000 (pre-war 2020). So the Russian media made Bakhmut the litmus test of how effective the Russian military force is. But it appears that they won't take that place.
So now they have turned to Soledar, a town of 10,000 (pre-war 2020), to make that their new litmus test. Some sources claim it has been taken, but it appears it is still contested.
If the Russians fail to take Soledar, I expect the Russian media will soon be talking about how they are on the verge of taking some town of 3,000. The Russians believe they will soon take some city or town of decisive importance this winter. They just don't know yet which one it will be. Perhaps it won't be a town. Maybe it will be a house in Bakhmut or Soledar, which will be declared as the "Pavlov house" of 2023.
