Getting SSLException

[gmarshall56]

Compiled (java 8). Then ran with:
java InstallCert localhost:3000

Getting:

Could not obtain server certificate chain

Also getting this exception using Java 11...

Looks like the exception relates to whatever you are serving from localhost. Is port 3000 serving SSL? Is there a certificate installed on your server? The exception is telling you "Could not obtain server certificate chain" on your localhost:3000.
