| ERROR: License key has been revoked | The key was used on multiple servers or payment failed. | Contact Erlyvideo support. Do not buy keys from unauthorized resellers. |
| Network error while validating license | Firewall blocking outbound HTTPS (port 443). | Whitelist license.erlyvideo.com and api.github.com (for update checks). |

A Flussonic license key is a unique, encrypted string that: flussonic license key
Q: Can I use one Flussonic license key on two servers? A: No. Each key is cryptographically bound to one specific server (by IP or MAC). Using it on two machines triggers an automatic revocation.
Q: What happens exactly when my Flussonic license expires? A: The media server continues running existing streams but refuses new connections. Recordings stop after 24 hours. You cannot change configuration. This gives you a window to renew without total outage.
Q: Does the free trial watermark disappear with a paid key? A: Yes, instantly after restart. You do not need to reinstall the OS or reconfigure streams. Q: Can I use one Flussonic license key on two servers
Q: My license says "Invalid MAC address." I'm using a virtual machine (VMware/KVM). A: Virtual MACs can change during VMotion or snapshot revert. Ask support to bind the license to a static UUID (Virtual Machine ID) instead of MAC.
Q: Is there a free or open-source alternative to Flussonic? A: Alternatives like SRS, Nimble Streamer, or MistServer exist, but they lack Flussonic’s unified API, Watcher surveillance features, and commercial support. For production streaming, the license key is a small price for reliability.
