   I've encountered exactly the same issue when using the socks5h proxy and httpx/httpcore/openai.

   The request hung for 25 minutes before finally failing with:

   Traceback (most recent call last):

   The above exception was the direct cause of the following exception:

   @tomchristie @graingert I noticed a linked PR has been open for 2 months...

   UPDATE: actually seems to be working fine on my end--the extended time period before failure was actually due to 2 successive retries that openai puts into their default parameters (I think). False alarm, sorry.
