That is the last block that I have here, Sun Aug 26 12:00:06 2018
I typically have 5 to 7 connections at any time, so I assume this is the actual state for the network.
My interpretation is that no one is mining at the moment.
Do you want to mine?
Prof, is this happening because you are Hard Turtling the blockchain? Please explain
No. Things should work for anyone who mines. At the current difficulty, you have to have an ASIC. I calculate that my 83 GHz/s Avalon will take maybe 15 hours to find a block, so there may not be many willing miners at the moment.
If you absolutely want a block, you should be able to rent-a-miner online, run your own client synced up to mine, and get satisfaction.
