Hello all,

I am trying to configure DOH over HTTP and I can't seem to figure out what I'm doing wrong. I have a nginx proxying the incoming request and don't need it on HTTPS.  Here's my config

*--- doh over http*
setACL({"0.0.0.0/0", "::/0"})
addLocal('0.0.0.0:7070')
webserver("127.0.0.1:8083")

newServer({address="1.1.1.1", pool="pub-unsafe-tier1",name="cloudflare"})
newServer({address="8.8.8.8", pool="pub-unsafe-tier1",name="google"})
newServer({address="194.242.2.2",pool="pub-safe-tier1",name="mullvad-noadblock",checkInterval=60})
newServer({address="84.200.69.80", pool="pub-safe-tier2",name="dnswatch1",checkInterval=60})
newServer({address="84.200.70.40", pool="pub-safe-tier2",name="dnswatch2",checkInterval=60})


addDOHLocal("0.0.0.0:9090",nil,nil, "/dns-query", { reusePort=true, trustForwardedForHeader=true })
```

When testing on the  locally, here's what I get:

$ curl  -H 'accept: application/dns-message'  'http://localhost:9090/dns-query?dns=AAABAAABAAAAAAAAA3d3dwdleGFtcGxlA2NvbQAAAQAB'

dns query not allowed

$ ...


Where am I going wrong?

Best,
Chandra
