Bitcoin node restart

Recently I had a power outage and my raspberry pi that shut it down. I did a complete re-installation and this is the 4th time I’m trying to restart my node. It seems I can’t get passed approx 20% synchronicity. I’ve done this in the past and it worked, however now it only stops syncing to a certain point. Is this due to the ordinal sabotage of the block chain that is making it more difficult to sync? Can I get some help please?
Thank you.

Please i need help about LNDHub i want to install it on my iPhone 6s

Are there any errors or warnings in the bitcoin-app logfile? Otherwise it‘s hard to figure out what‘s going on.
