500 internal server error on GET /passes/<norad-id> about satellite-passes-api

[redraw]

@viconnex based on the Cloudflare Ray ID, you are THE one I've blocked 👀. You were flooding the server, exceeding the redis operations quota. I can unblock your IP if you can fix your code. Seems like you were hitting the /passes endpoint in a while True loop maybe?

[redraw]

Hi, thanks for alerting. Reading the logs and seems like the redis cache reached the daily limit 🥵

I guess I could skip cache writes if hitting this limit, I'll take a look.

[redraw]

I could add Cloudflare on front to cache cached requests, but that will require a domain change.

[redraw]

Done. Now use https://sat.terrestre.ar and let's wait until tomorrow to reset the daily quota. I blocked a heavy bot that was consuming the quota.

Hello @redraw! Thanks for setting this up! However I get 403 Forbidden errors now 😅
I am blocked by the Cloudflare protection. The error message invites me to share my Cloudflare Ray ID: 88394dda2a0a9e8d. Does it help for debugging?
Thanks! 🚀

[viconnex]

LOL indeed! Sorry! My code calls the /passes endpoint every 10 seconds. What would be an acceptable delay for you?

[redraw]

No prob. Why every 10 seconds? passes don't change. Calculations tends to drift after 15 days of prediction, as those will require updated TLEs in the future. Every 1 day you should be fine.

[redraw]

Just unblocked your IP 👍

[viconnex]

Thank you! Yes you're right, I will change the code.
