I’m using trial license for wowza streaming engine. I can’t access the management page with error below " REST API Authorization failed when connecting to server: ([http://localhost:8087](http://localhost:8087)) " Would you let me know about how can I access that with trial license? ---

This could be an issue with your license key. Double-check that your license is installed properly by editing this file and confirming that no extra spaces or characters are present, beyond the exact strong of text that Wowza provided with your trial license.: `[install-dir]/conf/Server.license` Restart the Wowza Streaming Engine service to apply changes, if any. ---

Thank you Tim, but I already cheched that way. Is it authorization issue for trial?
