Getting timeout on digging pihole

gowtham · August 14, 2021, 3:58am

Hello, tried this blog post to deploy a container. I’m able to access the webui, but unable to access the DNS at port 53.

This is my fly.toml

# fly.toml file generated for <redacted> on 2021-08-14T08:38:00+05:30

app = "<redacted>"

kill_signal = "SIGINT"
kill_timeout = 5

[env]

[experimental]
  allowed_public_ports = []
  auto_rollback = true

[[services]]
  http_checks = []
  internal_port = 80
  protocol = "tcp"
  script_checks = []

  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 6
    timeout = "2s"

[[services]]
  internal_port = 53
  protocol = "udp"

  [[services.ports]]
    port = "53"

when doing a dig with the IPv4 (as well as IPv6), I’m getting the following:

dig google.com @<anycast ip>
; <<>> DiG 9.16.1-Ubuntu <<>> google.com @<anycast ip>
;; global options: +cmd
;; connection timed out; no servers could be reached

and telnet:

telnet <anycast ip> 53
Trying <anycast ip>...
Connected to <anycast ip>.
Escape character is '^]'.
Connection closed by foreign host.

not sure what i’m doing wrong?

gowtham · September 4, 2021, 5:57am

i tried with adguard too and it looks like i’m able to connect via TCP, but UDP somehow times out. may be a problem on fly.io side?

gowtham · September 26, 2021, 8:30am

any updates on this please?

jerome · September 27, 2021, 12:31pm

Sorry for the huge delay in responding to this. It seems to have slipped through the cracks.

Can you try re-deploying if you haven’t in the past week or so? We have some servers where UDP doesn’t work the way it should. Apps with UDP are now constrained to servers that do support it now. Your region might be unavailable though.

gowtham · September 27, 2021, 12:44pm

Thanks for looking into this. Anywhere I can track this issue? and what regions UDP is available now?

jerome · September 27, 2021, 12:57pm

The following regions should work for UDP: ams, atl, cdg, dfw, ewr, fra, hkg, iad, lax, lhr, nrt, ord, scl, sea, sin, sjc, syd, vin, yyz

gowtham · September 27, 2021, 7:00pm

thanks! please let me know if it’s available on maa.

gowtham · October 24, 2021, 10:12am

Hello, is the UDP support added for MAA region?

user19 · October 24, 2021, 1:38pm

I am also looling forward to UDP in ‘maa’ region. Any updates on this?
In addition to that I am also looking forward to regional ip-v4 in ‘maa’ region. I was able to allocate a regional ip-v4 for sydney but doing so for maa region led to an error
