I am running the latest stable release. After seeing this discussion and post I realized I also needed to update my testnet DNS seed nodes since 5.4.0 did not have those updated. Looking forward to 5.5 @ardocrat 
All is working fine now, so both Mainnet and Testnet seed can be added to the list
mainnet.fountainoffairfortune.it
testnet.fountainoffairfortune.it
