Blocked using JSON feeds

Hello, I regularly browse reddit at home on Firefox without issue, recently ive started using an rss feed on the command line which grabs the feeds by running e.g:
curl "https://www.reddit.com/r/selfhosted/hot.json" - On my command line It returns the error saying I'm blocked and responds with a 403 to get in touch with support.

I thought it would be worth asking here because this works fine with my home IP on the browser, its only my command line :( - Advice, TIA.
