Hi, this seemed an issue a few hours ago, it should all be sorted now, are you still having issues?
Could be coincidental, but the gateway error is a sign that an intermediate relay server is having problems along the route from you to the OpenAI endpoint, not typically an API failure.
This error means “temporary overload or error on the OpenAI side.”
If you wait a little bit, it will almost certainly go away.
And then come back sometime later.
You have essentially no control over this, other than waiting and trying again after a bit. (Use exponential back-off if you do this in a loop.)
