502 Orderbook Error on Start9

Currently having an issue with Jam's orderbook on startos.

It is giving a 502 error, according to the other admin it *was* working, but now it isn't.

[Error while loading the orderbook. Your current local setup might not support fetching the orderbook. Reason: The server reported a problem: 502 Bad Gateway]

We are running Start9 on a Kamrui mini PC, connected to Ethernet.

Some of the hardware specs are:
CPU: Alder Lake N97
Ram: 16GB DDR4 2666 MHz
Storage: 1TB M.2 SSD

We have version 0.3.5~1 of StartOS, version 0.3.0 of Jam, and Jam otherwise seems to be running correctly. My fellow admin is concerned that no transactions are happening, which I don't know how to check. All I know is that we are set up on the Earn tab in Jam, and that is the market maker role? Any advice would be greatly appreciated.
