I have a script that queries the API using the URL https://api.themoviedb.org/3/movie/539972?api_key=xxx&language=en-US and up until last night this call would work just fine, but now the calls from Chile and Brazil are taking around 40 seconds, while from Germany everything is working just fine. Using a browser in any of those places also gives me an instantaneous response.
Was there any change to the API that I'll have to update my script? By the way, my script only queries the API 5 times a day, so I don't think is anything related to rate limit.

Chile and Brazil is resolving the domain to the IPs below:

Sounds like something network related in South America. We don't run the CDN, AWS does, but I'd be curious to know what POP you're hitting in South America. What is the x-amz-cf-pop from one of those requests?

Request

curl -I -L "https://api.themoviedb.org/3/authentication?api_key=###"

Ok, so both of your SA requests are being routed to the same pop in Miami, and your Germany requests are being routed to France.

When you run those cURL commands, are they taking the same ~40 seconds to reply?

It's a hit-and-miss. I'm still investigating but it looks like it's related to IPv6. On my tests, all connections to v4 worked just fine. I'll keep you posted.

Hi Travis, I finally understood what's going on. The DNS is responding with a list of v4 and v6 addresses, and my script was trying to connect using the v6 address instead of v4. However, since my IPv6 wasn't properly set up, the connection started to fail. After fixing my IPv6 configuration, everything went back to normal.

I appreciate your support!

Happy to hear you figured it out! I've definitely seen IPv6 cause issues. I actually have it disabled on my own home network because my ISP does some weird things that was causing me some issues on the internet as well.
