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)

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.
