Too many requests for getting a deck image ?

I've been getting a error for too many request for printing a deck image surprisingly often. What exactly going on in the deck builder system? 
Is the system too new and fragile for handling workloads ?

How often are you pushing that button?

The deck image endpoint is rate-limited. I had it set to 10 requests per 1 minute. That means if you try generate more than 10 screenshots in a minute (which does seem excessive), then the system will automatically throttle you. This is a commonplace modern technique to prevent server abuse. 

I've updated it to 30 requests per 1 minute now, which is basically an image every 2 seconds, which should be more than enough.

It's also by IP address so it would be solely for you, however since we are proxied by Cloudflare it could have been throttling my Clouflare IP and in theory this could have been a big pool of users you shared with (incl bots). 

I've pushed out an update now anyway that fixes all these points. Can you try again and check if it works?

I only pressed once but it hanged up with a sandglass so i waited a bit. Reloaded the page to edit again and it worked just a few minutes ago. 
But it seems to be sensitive even when i press merely once and makes me wait until hours later to try again.
