Have you tried reconfiguring the server script?

sudo tron-ctl stop
sudo tron-ctl reconfigure

Set the hostname to the computer name.

sudo tron-ctl start

I have no idea if this will fix your issue. I used to run Spiceworks on a Ubuntu Server 20.04.2 LTS but I ran into a irreconcilable bug with it and development for it is currently on hiatus: What’s going on with Spiceworks Tools & Apps in 2021?

“Some of you may have noticed we didn’t reference the Help Desk Server (HDS) above. Unfortunately, we do not see substantial interest or adoption of HDS, especially when compared to CHD. When we look at what we need to accomplish this year with CHD, we’ve come to the hard decision that our best path forward is to concentrate our efforts there. This means we’ll discontinue development on HDS during 2021 following the release of v1.3 and re-evaluate our position at the end of the year.”

Which stunk a little bit considering I just built it like 3 weeks ago lol. I’m migrating us over to the Cloud Based version this week.

I also know my server required libreadline7 instead of libreadline8 in order to function. Perhaps it upgraded that?
libread7 can be found here: Ubuntu – Error
