You shouldn't need to configure anything, what browser are you using? I added some error handling to get more visibility, what happens if you navigate to a subreddit like https://reddtok.vercel.app/r/oddlysatisfying ?
Thank you, that worked. And after that, the main URL too
Not sure what happened. Tried it on Safari mobile
Glad it worked! Best guess is it may have been a CORS issue.
