Reddit proof link returns 502 Bad Gateway

I was using the keybase CLI version 0.7.2 to prove my identity on Reddit.

Cloudflare has a [KB article](https://support.cloudflare.com/hc/en-us/articles/200171846-Why-am-I-getting-a-cloudflare-nginx-502-or-504-gateway-error-) about this, so I opened an issue with them and sent my `traceroute reddit.com` output.

I worked around it by URI decoding the query string values and pasting the results into the Reddit Keybase proof submission form. My proof is [here](https://www.reddit.com/r/KeybaseProofs/comments/2l2xdp/my_keybase_proof_redditmekaj_keybasejmitchell/) and was accepted by keybase.

If this is a common problem maybe keybase CLI should generate more fool-proof output than a link.

No source file or test is named. Start by reproducing the Reddit proof link generated by keybase CLI 0.7.2 and compare the encoded query with the URI-decoded values that worked in Reddit; done means the generated proof flow avoids the reported 502 or clearly identifies the external failure.
