This problem may be due to self signed certificates that havenandhearth.com uses. To add an exception to Java;

Computer -> Open Control Panel -> Programs -> Java

Java Control Panel

tabs-> General|Update|Java|Security|Advanced

Security

exception site list

read this web page about how to add exceptions
https://www.java.com/en/download/faq/exception_sitelist.xml

Add a URL

Click on the Edit Site List button.
Click the Add in the Exception Site List window.
Click in the empty field under Location field to enter the URL.
URL should begin with http:// or https://
eg. http://havenandhearth.com or https://havenandhearth.com
Click OK to save the URL that you entered. If you click Cancel, the URLs are not saved.
Click Continue on the Security Warning dialog.

Make sure your version of Java is up to date. This error only shows up with older versions of Java. You should be running 1.8 update 144. You can update directly through the Java options (Windows: Control Panel > Java) or via java.com. It's suggested to allow Java to auto update. As long as Java is installed and can run through the web browser, all it takes is going to a bad website to have virus or other problems. (Note there are other causes of this error, but a user probably won't be seeing them on released software unless it's a major bug.)

You may need to fully uninstall and reinstall Java, too.

If you're running any 3rd party security software, please see my note at the bottom.

This problem may be due to self signed certificates that havenandhearth.com uses. To add an exception to Java;

Except the cert the game uses isn't self signed. The cert the SSL login is, though, if anyone wants to log into the website via HTTPS.

There should be no need for exceptions* or installing the cert onto the computer manually unless there's another problem. Adding an exception for Haven to Java's security hasn't been necessary in a while (since Java v8 was released a year or so ago at least). The exception to that I can think of is if Java's security is set to "Very High," and the certificate cannot be verified by the certificate trust chain. I can think of a few possible failures, but nothing that can be easily diagnose over the Internet, or even related to the client computer running the code.

To note, the Seatribe certificate is issued to HB Seatribe by GlobalSign CodeSigning CA. This can be viewed through the Java options, Security tab.

*Note: If using a 3rd party firewall or other security software, adding exceptions to that software may be necessary. If they aren't there, then issues running any app or other software can experience odd crashes. Typically there's other errors that occur, though something like this one is possible.

I had the same problem after installing new java.

Still doesn't work. It loads but then closes almost instantly and displays this error: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Anyone know how I can get the right certificate?

[MagicManICT]

I sent a PM to the devs on this. The only things I can think of causing this have been mentioned. There may be another cause I've overlooked, though.

This sounds different from what the OP reported, since you say that the client "closes". Is this a JNLP error or an in-client error? Can you post more details, like tracktraces or wrapped exceptions?

[CelticWarrior]

I didn't have any idea what you said loftar. when I say it closes the whole window closes and a small error window pops up. I think it has something to do with the certificate.

[loftar]

a small error window pops up

Please post more information about said window. What does it look like, and does it contain further information that you can post?

[CelticWarrior]

Now it loads the login screen at least. However, when I type in my username and password and click login, it gives the error message below. I think it has something to do with the certificate.
