I have an nginx proxy based on openresty (https://openresty.org/en/), which is running in a docker container. It's simple proxy like:
proxy_pass https://foobarstorage1.z6.web.core.windows.net/;
proxy_http_version 1.1;
From time to time, we get an error like bellow and I have no idea how to debug it.
It cannot be reproduced but it happens from time to time and I have the feeling it might have something with IPV6 but I am not 100% sure.

Any tips are welcomed.
