OpenDNS error: "http2: could not negotiate protocol mutually" #22

Hi Pawel,

Lately OpenDNS seems to give an error (latest version of code):

$ ./dingo -port=53 -odns:workers=10 -gdns:workers=0 2017/01/05 14:29:40 starting 10 OpenDNS client(s) querying server 67.215.70.81 2017/01/05 14:29:40 dingo ver. 0.13 listening on 127.0.0.1 UDP port 53 2017/01/05 14:29:43 resolving index.hu./A 2017/01/05 14:29:43 http.Do(): Get https://67.215.70.81/A/index.hu.: http2: could not negotiate protocol mutually

Google works all right.

Also, thanks for the great software, keep up the good work!

Hi Kristóf,

Thanks for using dingo. For OpenDNS, you need to start dingo with the -h1 option that switches back to HTTP/1.1 mode. Unfortunately, www.openresolve.com doesn't support HTTP2 (yet?).

Thank you for the answer, Pawel!

Do you think there would be value in downgrading the HTTP automatically (silently or not) if the user choose to use Odns?

implemented in https://github.com/pforemski/dingo/commit/42078d501f78b2c2ed471fd855eb3a824d8725f3 :)
