I received a notification for the Netbeans 15 available. However in Netbeans 14, I attempted to use "Help...Check for Updates" (I think this may be checking for plugin updates but was hoping for it to find the Netbeans 15 update as well) and received a failure when attempting.
Window showed Check your network connection, verify that your proxy settings are configured correctly in the NetBeans IDE, or try again later. I believe it is caused by reference to "update.netbeans.org" site as mentioned in the output in the IDE indicating INFO [org.netbeans.ui.indexing]: Indexing finished, indexing took 0 ms. *INFO
