PrometheusEndpointServer throws an exception, after which the endpoint is not available and not restart

[NitroLine]

I have django app on uvicorn. I use PROMETHEUS_METRICS_EXPORT_PORT_RANGE=range(8001, 8011) to start metrics on each uvicorn worker. It works fine.

But after some netowork error on server, some workers print execption:

Exception occurred during processing of request from ('106.75.72.22', 52046)
Traceback (most recent call last):

Or

And some targets in prometheus start show error context deadline exceeded. (I saw such Traceback four times in logs, and four targets are down now)

So I think the PrometheusEndpointServer process has crashed and won't restart, I'm losing some metrics because of that. It would be cool if the exporter server automatically restarted if it became unavailable.
