Getting Random HttpClient.Timeout messages

[George-Smy]

I'm getting the following message sometimes:

"The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing. and The operation was canceled."

But a retry with the same prompt after a second or two goes straight through and returns results. I'm calling OpenAI.DLL using VB.Net so not really doing anything except building a OpenAIService with an APIKey, setting the model and a couple of prompts and calling.

I can see the time that I start the call and I see that a lot of times the message appears within 10 seconds or less so it makes me wonder if that's a default message and something else is happening? It certainly isn't the 100 seconds referenced. I did also see a Cloudflare message today as part of an error return.

Is there some additional information on what could cause this?
