Unfortunately, the on-prem release hasn’t been updated since March of 2018.

You are on a product that has had no updates or patches for almost 2 years.
v.8 was placed on hold and no one realistically expects a new on-prem version (at least not in the near term).

So, most evidence points to On-prem being a dead product (with only a possibility that it will be revived in the future) and cloud the only real path forward if you wish to use Spiceworks.

I’d look at migrating to Spiceworks Cloud or a different product.
