This is a problem with the connection. It is probably not really random. Are they corporate users? They may be having a problem with rtmp. You can try using rtmpt. You should enable port 80. Change /conf/VHost.xml /HostPort /Port “1935” to “1935,80”, then restart Wowza. Then try: rtmpt://[wowza-address]/[appName] If you cannot enable port 80, you can use 443, or any port really, even 1935, but if it is anything other than 80 you have add that port: 443 is the best choice actually. Change /conf/VHost.xml /HostPort /Port “1935” to “1935,443” or “1935,80,443” Then use: rtmpt://[wowza-address]:443/[appName] This will also use rtmpt, but it is not the best option to overcome this problem: rtmpt://[wowza-address]:1935/[appName] You can use a protocol rollover scheme so that clients that can will connect with rtmp and others will try rtmpt: [http://community.wowza.com/t/-/37](http://community.wowza.com/t/-/37) If you can, it would be a good idea to test this with a user that is having this problem. You can setup a player that uses rtmpt.
