Network Connection Lost..Reconnecting ...Errors

Good afternoon!
I can’t go into my wallet! He did not launch it for more than a year and now he writes that he cannot boot. What should I do?
Wallet version 0.11.1 #
Network Connection Lost…Reconnecting
Errors after failing to connect


That version is ANCIENT. Current version is 2.4.1.

Make sure you have the seed phrase, back up the existing wallet directory, install 2.4.1 and restore the wallet from the seed phrase.

FYI, the network protocol the nodes use to communicate with one another has changed so that the old version can’t even read/decode the data currently on the network. This happened about a year ago.
