So I had a very brief power outage today and now sparrow won't connect to the node again. So strange. My only guess is that because bitcoin core didn't shutdown properly it's causing some issue. Am I just going to have to reinstall bitcoin core everytime my pc shuts down abruptly?
[/quote]If the issue only a corrupted file brought by the abrupt shutdown and only in Bitcoin Core, then a --reindex might solve the issue.
It's a command-line option and not a command so; to use it, Bitcoin Core should be started with that parameter.
