Hi,
the h2 test suite has tests with http/2 in the front and a standard proxy_http
to localhost. When running the test suite against trunk, the tests run into a
failed GET on a proxy. The request hangs 5 seconds and the fails reading the
status line, as seen below. The proxy is defined as:
<Proxy "balancer://https-local">
BalancerMember "https://127.0.0.1:SUBST_PORT_HTTPS_SUBST"; hcmethod=GET
hcuri=/
</Proxy>
...
ProxyPass "/proxy" "balancer://http-local"
ProxyPassReverse "/proxy" "balancer://http-local"
Typical log:

What can I best do to further debug this?
Should I disable the balancer and see if the problem persists?
Help appreciated, thanks!
