We did over 2k requests for OpenAI API on this site in the last month, and we have no errors like that in our logs.
I got into another site we host who heavily uses OpenAI, with 80k requests this last month and they have zero Faraday errors, and only two “Connection Reset by Peer” errors in the period.
Is it possible that you have something bad in the networking of your server? I had Errno::ECONNRESET (Connection reset by peer) once because of a faulty NIC driver.
