Resolving [google.com] using 127.0.0.1 port 53
Steps to Reproduce
- Installed dnscrypt-proxy2

- Started the dnscrypt-proxy2
- dnscrypt-proxy2 cannot connect to the DOH servers over the proxy as it couldn't resolve the proxy using the bootstrap_resolvers

Other Comments
It works with the following scenarios, so the http_proxy domains are likely not resolved.
- Disable the http_proxy
- Use IP instead of the domain for the http_proxy (e.g., https://192.168.1.100:1883 instead of https://proxy.acme.com:1883)
