You can try backing up and reinstalling your wallet. To backup, ensure you write down your passphrases on paper and keep them safe. To export your passphrase, open your wallet, choose your address, navigate to 'Manage', and select 'export passphrase'. Be sure not to share this with anyone. Once you've secured your passphrase, you can proceed with reinstalling the wallet.

One possible issue could be the VPN. If you're using one, turning it off might help resolve connectivity issues. However, since you've mentioned that the issue persists with the VPN off, it might not be related to that.
