Help: Cannot install additional blueprints, Unknown Error with Websocket API

I recently installed Home Assistant OS 8.2 on an Odroid-C4, and I have not been able to figure out the following issue.
Every time I try to import a blueprint from the Blueprint Exchange, I get “unknown error” on the dialog.
Checking the logs, it appears to be a WebSocket issue. Any ideas?
