Problem: All of a sudden, audio streaming radio stations stopped working using Astaro version 6.312. Also noticed some other sites were having issues. The problem was that that they were sites that did browser checks and then would error out saying that active scripting needed to be enabled. Didn’t realize it at first but both issues were related.
Solution: Turned the anonymity level on the HTTP proxy, within my Astaro Firewall, to none and it fixed the problem.
