Front Door responds with OriginTimeout after ~4 seconds despite larger timeout setting

Hi!

We have 90 seconds timeout configured as the origin timeout setting. However, from time to time Front Door fails just after 4 seconds with OriginTimeout setting, something like below. It looks like these requests don't even reach the origin. What could be causing the timeout on the FD side?

"timeToFirstByte": "3.997",

"timeTaken": "3.997",

"httpStatusCode": "504",

"httpStatusDetails": "504",

"pop": "CHG",

"cacheStatus": "CONFIG_NOCACHE",

"errorInfo": "OriginTimeout",

"ErrorInfo": "OriginTimeout",
