Jux Coming Soon Page not showing even though plugin is activated

Hello, my jux coming soon page is not showing. It was working a few weeks ago.
The launch date is set correctly to 2019 (had this issue already on an other site)
It just stopped appearing. Joomla is updated to 3.8.12
perhaps it is the php version? Currently on 5.6.37 (hasn't changed since it was working)
pese help

Thank you very much, I solved it re-installing the plugin ( thought that is what you where about to do, but since you are now off line and there is a big time difference I have followed through with your hint myself! Not sure why it wen't down in the first place, but the important thing is it functioning again!!
Thank you!
