Old Safex BTC Wallet

I kept the old versions of the safex wallet (v006, v007, etc) and used to use them for setting up new btc addresses, as well as sending btc from time to time.
My Problem is that none of those versions seem to connect to the btc blockchain anymore, and I get an error that I am not connected to BTC. I still have all the private keys associated with the btc address, but wondering why the old safex btc wallet software may not work anymore. I have tried all older versions as well as up to v007. I last used them a few days ago to send btc without any issue. Thanks for any help!!

EDIT 1/11/2021 : The old wallets are working and syncing up fine now. I’m not sure what happened.
