Shard stall

Hi @binh, here’s the latest: I have a bunch of pnodes. 4 of them still cannot be accessed via command like chain-info or browser, however all of them have an IP and I can ping them. My other pnodes can be accessed. ALL of the pnodes are connected and show online in the Node Monitor. The 4 that can’t be accessed are original pnodes from the first batch of nodes back in 2019, all my other pnodes are newer. Just wondering if that has anything to do with it. I’ve power-cycled them 10 times each but still nothing. Any ideas?
