Sorry for this catchy title, but I wanted to bring attention to you.
v3.2.3-stable-sdk2, the SDK uses nbandroid(dot)org as repository for NBAndroid.
Unfortunately, this site has gone offline. Problems would arise, when someone else is registering nbandroid(dot)org and starts hosting malware “nbandroid updates”.
Thus it is recommended that you remove/disable (removing will only work after said release) the NbAndroid 8.1 Update Center under Options → Plugins → Settings.
Note that this action is necessary for every instance you have which is not a clean install. Even the new version would only add the up to date NBAndroidV2 Repo (which btw you are encouraged to try out, it would be cool if Android Dev would be more SDK Native again), but not delete the old one.
If you don’t do that, I think you are also secure for the moment, because at least our jme update center had it’s own certificates in place to ensure that the modules can’t be tampered with, but I don’t know if such mechanisms are in place for nbandroid.
