Silicon Valley server only use once apikey then terminated!

I don’t know why. I registered an OpenAI account and then generated an APIKEY for use on a server in Silicon Valley, but just sent two requests and gave it to me for Terminated. Then I re-registered an account and also generated an APIKEY for use on this server. Now I only requested once and gave it to me for Terminated. What is the situation? Is there a problem with your strategy?
