Make sure your wallet is up-to-date and pick a trusted community remote node like:

• https://monero.stackwallet.com:18081/
• http://node.sethforprivacy.com:18089/

Edit: Removed the kyun node. Apparently it's not an official kyun node and ran by an anon.

http://hashvaultsvg2rinvxz7kos77hdfm6zrd5yco3tx2yh2linsmusfwyad.onion:18081/ Also specify a known trusted node in Tor, such as the one from hashvault-Pool.
