LXSeries Lighting Software

I am trying to use a temp licence. In the log, I am getting "Exception checking temporary license java.io.IOException: Server returned HTTP response code: 403". I have reinstalled the software to 2.9.3 (19912.1)

Your temporary license appears to be working. It is likely that the root certificate for the server that verifies temporary licenses is newer than the root certificate that is included in the version of Java you are using.

The explanation is sort of technical. When LXPlan contacts the server to verify your temporary license, the connection is by https. Https is a secure connection. The security comes through a series of certificates each one using a higher level certificate to verify and trust the one that is being checked. Java has a file called "cacerts" that contains a bunch of root certificates which are the highest level certificates. These change slowly over time. An older version of Java may not have the necessary root certificate to trust a newer server's certificate.

The solution is to update your copy of Java.

The installer for LXPlan that includes a copy of openJDK will install a version of Java alongside the LXPlan application that is new enough. This copy of openJDK will not change the version of Java used by other applications on your computer. So, that may be the simplest way to resolve the issue. Otherwise, if you are using Oracle Java 1.8 to run LXPlan, you need to update that.

The other possibility is that the server had a problem with its certificates. When this happens, the hosting company will resolve the issue and the link will work again. This might have been the issue. But, by the time I checked your temporary license, it was fixed.

After further investigation, It turns out that there was a different server change that was likely causing the issue of your temporary license not working. This is fixed and a new version of LXPlan is available for download 2.9.3 (19919.1).
