FHIR validation fails all of a sudden


I was using FHIR validation and it was validating successfully. However, it gives me error nowadays. The error is attached. May I know what went wrong all of a sudden?

I’m using the following command to run FHIR validation

wget -O test.json; java -jar org.hl7.fhir.validator.jar ./test.json -defn definitions.json.zip;

I use the following resources:

Validator Zip



We’re having problems with the stability of the terminology server that supports validation. That error is that you can’t connect to that server.
