How Do Listeners Tune In to Centova Cast Through the Port 80 Proxy?

Updated: 8 October 2026 · Applies to: Centova Cast v3 (from Centova documentation); link tests with curl 8.14.1 and 8.22.0 against Icecast 2.4.4 behind nginx 1.26.3 on Debian 13

Listeners tune in through the proxy with the proxy tune-in links that Centova Cast creates for your stream. Once the proxy is enabled for your account, those links appear on the Quick Links page of your Centova Cast control panel and on your stream's public start page. Send listeners that link, or use it in your website player. They open it like any other stream link and change nothing in their player, because the link uses the normal web port (80 for http, 443 for https) instead of the stream's own port, such as 8000.

Before you start

The proxy has to be switched on for the server and permitted for your stream account; the Centova Cast port 80 proxy explains both steps. If you cannot find any proxy links in the steps below, it is not enabled for your account yet. Ask your hosting provider or server administrator to enable it.

Find the proxy tune-in links

1. Log in to Centova Cast with the address from your welcome email (often a link ending in :2199).
2. In the menu on the left, under General, click Quick Links.
3. Look under Tune-In Links. According to Centova, the proxy links are shown there once proxy support is enabled for your account.
4. Tell the two kinds apart by the port: a direct link carries the stream port, such as :8000, while a proxy link uses a standard web port, so it shows no port number at all, or :80 for http and :443 for https.
5. Copy the proxy link and play it yourself in a browser or media player before you share it.

Your start page offers the same tune-in links to visitors. Its address is in the Quick Links box at the top of the same page.

Share the link with listeners

• On your website: use the proxy link in your player code. If your site runs on https, use the https version of the link, because browsers block http audio on https pages. See how to add an online radio player to your website.
• By email, chat or social media: share the start page or the proxy link itself.
• Apps and directories that ask for a stream URL: give them the proxy link if many of your listeners are at work, school or on public Wi-Fi.

What listeners need to do

Nothing special. They click the link on your website or start page, or paste it into any player that can open a network stream address. There is no proxy setting to enter in the browser or player: the proxy runs on the server and the listener only sees a normal web address.

Test a link from the command line

curl shows quickly whether a stream link works and, if not, why. We ran these checks in a container against an Icecast stream on port 8000 behind an nginx proxy on port 80; replace the addresses with your own links.

A working link returns HTTP 200 with an audio content type and keeps sending data until curl stops it:

$ curl -sS -D - -o /dev/null --max-time 3 http://127.0.0.1/proxy/testradio/stream
HTTP/1.1 200 OK
Server: nginx
Content-Type: audio/mpeg
icy-name: Old Station Name
...
curl: (28) Operation timed out after 3068 milliseconds with 100800 bytes received

A port that a firewall silently drops (the typical office or school network) gives a connection timeout and no data:

$ curl -sS -o /dev/null --connect-timeout 5 http://192.0.2.10:8000/stream
curl: (28) Connection timed out after 5001 milliseconds

A port where nothing is listening (stream stopped, or a wrong port in the link) is refused straight away:

$ curl -sS -o /dev/null --max-time 3 http://127.0.0.1:8010/stream
curl: (7) Failed to connect to 127.0.0.1 port 8010 after 0 ms: Could not connect to server

A wrong mount point reaches the server but returns 404:

$ curl -sS -o /dev/null --max-time 3 -w "%{http_code}\n" http://127.0.0.1/proxy/testradio/live
404

If the direct link times out on a listener's network but the proxy link plays, the proxy is doing its job.

If the proxy link does not play

• No proxy links on Quick Links: the proxy is not enabled on the server, or not permitted on your account's Limits tab. Only the administrator or your host can change this.
• Neither link plays: check that the stream is online (Start under Server in the menu) and that a source (AutoDJ or a live DJ) is connected. See my server is online but nobody can tune in.
• The direct link plays but the proxy link fails: the proxy itself needs attention on the server side; send both links to your host.
• The player on your https website stays silent: use an https stream link (streaming over HTTPS).
• A listener still cannot connect on port 80: some networks filter streaming audio itself, not only unusual ports, and a proxy cannot get around that.

Ucartz radio hosting

If your stream runs on Ucartz Shoutcast and Icecast hosting and you do not see proxy links, open a support ticket and ask for the proxy to be enabled on your stream account.
