Using a proxy with my HTTP Request isn't working & I'm losing my mind lol - Error Code 303

[mc1718q]

Hi everyone,

I’m trying to make an HTTP request to this endpoint: https://oauth.reddit.com/api/submit.

Without a proxy, the HTTP request works perfectly, and I’m able to successfully post on Reddit. However, as soon as I add a residential proxy, I encounter this error:

• Error 303 See Other
• Details: cache-muc13941-MUC 1723950213 4032929749
• Server: Varnish cache server

The strange thing is, when I use the same proxy to make an HTTP request to https://httpbin.org/ip, it works perfectly and returns the correct IP.

However, when I attempt the request to the Reddit endpoint, I consistently get this error.

I’ve tried using various types of proxies—residential, static, mobile, both HTTP and HTTPS—but nothing seems to work. I always end up with the same error.

I’ve been stuck on this issue for three days now, and it’s driving me crazy. If anyone has encountered something similar or has any suggestions on how to fix this, I would greatly appreciate your help!

Thanks in advance!

Hey @mc1718q,

The message you are seeing is coming back from Reddit and it is sadly something we don’t control. A 303 is a pretty vague error code and I can’t see anything in Reddits docs for 54113

It could be that Reddit just doesn’t like your proxy, If you set the node to include the full response and to not error you may see more data in the body but this sort of issue is something that will be better taken up with the Reddit API team.
