Polygon API outage causes API requests to hang?

[bdowling]

This is my first time trying the polygon API, so I may be doing something wrong, but I think perhaps the API is under maintenance this evening, as https://api.polygon.io is returning:

Error
Application not found or under maintenance.

While in this state, attempting to use api.polygon appears to just hang, haven't dug into why:

import alpaca_trade_api as tradeapi
api = tradeapi.REST()
aapl = api.polygon.historic_agg('day', 'AAPL', limit=10).df

print(aapl)

(never returns)

This particular issue may be an odd issue on my dev system. I identified that I can make polygon requests from a web browser to the API, but from this particular opensuse dev system the request hang, even with wget/curl. Hard to debug exactly what is happening with the SSL, not sure if it is SSL related.

(edited) So this is odd, why am I seeing a self-signed cert from linux, but not in a chrome browser?

$ openssl s_client -quiet -host api.polygon.io -port 443
depth=0 O = Acme Co, CN = Kubernetes Ingress Controller Fake Certificate
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 O = Acme Co, CN = Kubernetes Ingress Controller Fake Certificate
verify error:num=21:unable to verify the first certificate
verify return:1
GET /v1/historic/quotes/AAPL/2018-2-2?apiKey=XXX HTTP/1.1
Host: api.polygon.io

^C

Above appears to hang when I specify my API key, but does return Invalid / Missing if I specify the wrong one. Also fails to return even if I add a limit=10.

I'm closing this. It appears the dev system I was having problems with will not connect with TLSv1.2 properly, which the polygon API appears to require. Additionally, -servername api.polygon.io is required for the s_client test to support the SNI of your frontend.
