Stream key or server URL not accepted when saving

Stream key or server URL not accepted in Connections? What each message means, from "The stream key does not look right" to a Vimeo URL refused, and how to fix it.

Updated November 5, 2026 · 4 min read

When you add a network by stream key in Connections, StreamLive Pro checks the server URL and the key before saving. It refuses a URL that does not start with rtmp:// or rtmps://, an address that belongs to another service, an address on a private network, and a key that contains a URL, spaces, or the wrong format for that network. The message says which of these it is. In almost every case the fix is to copy the two values again, each into its own field, from the stream settings of the network itself.

These checks run when you save, so a mistake is caught before you go live instead of during the broadcast.

Steps

1. Open the network's stream settings. On the network itself, find the page with Server URL (or Stream URL) and Stream key. The card in Connections links to it and lists the steps for that network.
2. Copy the server URL alone. Use the copy button on the network's page if there is one. A correct address starts with rtmp:// or rtmps://. The card shows what a correct one looks like.
3. Copy the key alone. Click into the key field, select all, and paste only the key. A key is never a URL.
4. Check the card. The address must go into the card of the same network. For a service that has no card of its own, use Custom RTMP or Custom SRT: Stream to a custom RTMP or SRT server.
5. Save again. If the message changes, you fixed one problem and the next check found another. Read the new one.
6. Test before the real broadcast. Tick the new destination with one other channel and check on the network that the picture arrives.

Why StreamLive Pro checks the address

Each card knows the ingest servers of its network. When the address belongs to another known network, the message names it, because that is the most common slip when several stream settings pages are open. Networks that hand out changing server names, such as LinkedIn, are checked only for the scheme (rtmp:// or rtmps://) and the key, so there a wrong event key passes the check and shows up only on LinkedIn: How to go live on LinkedIn with a custom stream.

For every network, an address on a private or local network is refused, so a stored address can never point inside a network.

Vimeo Live

The Vimeo Live card accepts only an RTMP or RTMPS address on vimeo.com and a key of at least 8 characters with no spaces. The URL and the key come from the live event on Vimeo, and a one-time event has its own key. Setup: How to stream to a Vimeo live event over RTMP.

When the key is accepted but nothing arrives

The checks confirm the shape, not that the network will accept the key. If the destination saves but the network stays empty during the broadcast, the key is usually from an older session or event. Instagram, TikTok and LinkedIn give a new key per session or event. On X a Producer source keeps its key, but each broadcast needs its own Broadcast on that source in X Media Studio.

When to contact support

If a value copied straight from the network's own page is refused, write to [email protected]. Send the name of the network, the exact message, and the first part of the server URL up to the host name. Never send the stream key: anyone who has it can stream to your account.

Frequently asked questions

Why does StreamLive Pro say my stream key does not look right?

The key is cut, contains a space, or does not match the format of that network. Copy the key again in full from the network's stream settings, and paste only the key.

What does "That is a YouTube address, not Twitch" mean?

You pasted the server address of one network into the card of another. Use the card of the network the address belongs to.

Why is my Vimeo URL rejected?

The Vimeo Live card takes only an RTMP or RTMPS address on vimeo.com, from your Vimeo live event. Copy the RTMP URL from the event's stream settings again.

Can I add a server that has no card?

Yes. Use the Custom RTMP or Custom SRT card with the server address and key from that service.

The key was accepted. Why is the network still empty?

The check confirms the format only. A key from an older session or event is accepted but rejected by the network. Paste a fresh key from today's session.
