Getting Error: java.lang.IllegalArgumentException: Not a valid domain name: '192.168.0.202' in jhipster uaa project

Question

I have created a jhipster gateway and micro-service project along with a UAA server. It is working fine in my local environment. However, when I try to deploy it to a server and run it, I get an error similar to the below when I try to log in from the server-deployed gateway project:

Not a valid Domain name

Error :

Any help is appreciated.

Have you tried changing the IP address to a domain name (Eg: `localdomain` instead of `127.0.0.1`)? Have you tried [using `InetAddress`](https://stackoverflow.com/a/10554447/2225787) to get a host name and domain? — Agi Hammerthief, Jan 25 '18 at 06:55
Looks like that API in Guava works only with actual DNS domain names and not with IP addresses. — Jim Garrison, Jan 25 '18 at 08:07

This was fixed recently in JHipster's generator by this pull request.

To fix it locally in your project, edit OAuth2CookieHelper.java (in the security/oauth2/ package of your Java folder). Add an extra check for IP addresses before parsing the address as a domain name.

// add this import
import com.google.common.net.InetAddresses;


    // add this if-statement surrounding the domain name parsing
    // if it isn't an IP address
    if (!InetAddresses.isInetAddress(domain)) {
        // strip off subdomains, leaving the top level domain only
        InternetDomainName domainName = InternetDomainName.from(domain);
        if (domainName.isUnderPublicSuffix() && !domainName.isTopPrivateDomain()) {
            // preserve leading dot
            return "." + domainName.topPrivateDomain().toString();
        }
    }
