I am trying to make a XTZ delegation. Downloaded the Tezbox, but shows " Error Level N/A Not Connected https://mainnet.tezrpc.me " what's wrong for my tezbox. And how to fix this?
Tezbox is no longer a supported wallet. Please migrate to galleon, ledger live or kukai among others.
A tutorial on how to migrate from tezbox to galleon is available on the official site
