Wallets and Core "syncing" but has not for 5 days

The last block and transactions from my wallets and core have been 5 days ago. No new blocks have been validated and the wallet and core state they are “syncing” with no new validations. I tried rebooting and also tried reflashing the SD. But it seems to still be stuck with nothing progressing.

Please help.
