Problem processing credit cards

Anyone on 8.03 not using ESDM having an issue processing credit cards? We were fine yesterday, and now today we get the -1 error “can’t contact input host”. I contacted Paypal and they said they aren’t having a problem and haven’t made any changes to Payflow plus lately. Epicor said they can’t help because they don’t support processing credit cards pre ESDM.
