Unable to access StockTwits API from Express App hosted in Google App Engine

Question

I am able to access the StockTwits publicly available API: https://api.stocktwits.com/api/2/streams/symbol/:id.json from my express app when trying from local machine.

However, whenever I try to host the app from Google App Engine, I get the below error:

Is there something special I need to take care for using the app if I host on Google App Engine?

Answer 1

Same issue, even for authenticated requests. I wouldn't be surprised if the IP range from app engine is blocked due to a bad actor spamming the StockTwits API.
