Answers · Your interview

Viva cannot connect on my school network

Some school and office networks block the service that carries the conversation audio. Viva retries through vivaproof.com on its own; if that is blocked too, try another network or give IT the list below.

If you see "Your network is blocking the voice service", nothing is wrong with your account or your work. The page loads its call software from the voice service directly; when a school or office filter blocks that, Viva automatically tries once more with the same software served from vivaproof.com. You see this message only when that second route did not get through either, which usually means the filter blocks the voice service as a whole.

  1. 1

    Try again on a different network: a phone hotspot, or home Wi-Fi. The conversation works the same anywhere.

  2. 2

    If you cannot change networks, choose "Continue by typing" on that screen. You get the same interview and the same questions, typed instead of spoken, and it is marked the same way. Your teacher sees that you typed and why.

  3. 3

    If the school network is your only option, send this page to your teacher or IT. Once the service is allowed, come back and press Start conversation again. Your submission is unchanged.

"Could not connect to the voice service"?

That message means the page loaded but the call itself did not get through: a filter that refuses the voice service's connections, or Wi-Fi that dropped just as you pressed Start conversation. Viva never reached you, so nothing was recorded and it does not count as an attempt. Press Try conversation again. If it fails again, use a phone hotspot or another network, or choose "Continue by typing" under the message. If you leave and come back later, the page shows Start conversation again.

For IT: what to allow

Over TCP 443: *.daily.co, *.dailywebrtc.com, *.dailywebrtc.net and prod-ks.pluot.blue. vivaproof.com already serves the page and, when c.daily.co is blocked, the call software itself, but the conversation still needs the voice service for signaling and audio. For the audio itself: stun.cloudflare.com and turn.cloudflare.com on UDP and TCP 3478, TCP 5349 and TCP 443; *.stun.twilio.com and *.turn.twilio.com; and UDP 23000 to 26999 and 40000 to 49999 to *.wss.daily.co. Daily publishes its current server addresses at ip-info.daily.co.
