SSL errors on download

Hi,

I automatically install opm libraries when deploying OpenResty. This has a tendency to fail due to SSL errors from the upstream when performing this on AWS instances in the Sao Paolo region (sa-east-1). The other regions work fine.

docker run --rm --entrypoint=/usr/local/openresty/bin/opm --name lua-installation -v /usr/local/openresty/site/lualib/:/usr/local/openresty/site/lualib/ openresty/openresty:1.13.6.2-2-alpine-fat get pintsized/lua-resty-http

[10:31:32]   stderr: |-
[10:31:32]     * Fetching knyar/nginx-lua-prometheus
[10:31:32]     curl: (35) error:14004438:SSL routines:CONNECT_CR_SRVR_HELLO:tlsv1 alert internal error
[10:31:32]     ERROR: failed to run command "curl -sS -i -A 'opm 0.0.5 (x86_64-linux-thread-multi, perl v5.26.2)' 'https://opm.openresty.org/api/pkg/fetch?account=knyar&;name=nginx-lua-prometheus&op=&version='"

From my local machine it works fine and uses servers in DigitalOcean Singapore.

$ dig +short opm.openresty.org
v2.openresty.com.
188.166.239.230

From my Sao Paolo instances it fails and uses DigitalOcean US servers.

11:01:30 ~ ip-10-102-134-106 % dig +short opm.openresty.org

Start by reproducing the documented docker run command and compare DNS resolution and download behavior between the working and failing regions. Inspect the opm package-fetch entry point and its TLS or upstream request handling, using the reported curl error as the starting symptom. Done means package downloads work reliably from the Sao Paulo AWS region or the failure is clearly diagnosed and documented.
