We are getting HSE_REQ_SEND_RESPONSE_HEADER failed with error=87 (0x00000057) on a 302 redirect proxied by TC connector 1.2.46. I can see the 302 response come over from TC and it looks legit. Trace logs below. Anyone else running into a similar error or perhaps some clue as to why this can be happening?
