Video Server Error

‘RTMP server not found’ error on the browser?

Check if any firewall is blocking the RTMP streams.
Please contact your network administrator or Internet Provider. This could happen when you try to access the stream from your office or campus networks.


Server error (troubleshooting)

Did you receive such an error while trying to watch videos:
Server not found rtmp://r.acca.opentuitioncom.netdna-cdn.com:80/play

Please complete those steps below and send us back the results by email (admin@opentuition.com).
– your location,
– your IP address, (get it here>>)
– check what Datacenter is hosting video (click on this link: http://debug.netdna-cdn.com/ and send back the result
– send the results of traceroute and ping (see below how to get this)

ping p.acca.opentuitioncom.netdna-cdn.com
tracert p.acca.opentuitioncom.netdna-cdn.com

– send a link to a page where the video is having problems

so we can forward it to people who host our lectures, and they will check it


Please note:

If you have received in Ping results for example:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
It means, connection to server with lectures is fine – but you are behind a firewall – so you have to contact your internet provider for help, and there is no point in sending us the results.


PING and TRACERT On Microsoft Windows computers:

In Accessories you will find a program called: Command Prompt

 

Please type / copy these 2 commands one at a time, press enter and when you receive the results, please save/copy it  and email it to us

ping p.acca.opentuitioncom.netdna-cdn.com

tracert p.acca.opentuitioncom.netdna-cdn.com

Please send all your results here: admin@opentuition.com  so our video hosting provider can investigate your problems.

      @clotel, My network administrator turned off my firewall completely and tried to access the lecture in both IE and Firefox. Both IE and Firefox showed the same “server error” message. Hope you can help me to get back in and continue preparing for exams.

      • Profile photo of admin says

        Well, you see videos work for most users,
        Did you try another computer? – to see if this is only happening on yours..

        Please also check with the internet provider,

    • Profile photo of admin says

      also, please send by email (admin@opentuition.com)

      – your location,
      – your IP address
      – example of file causing/having problems
      so host provider can check this issue further,

      thanks

      if it is not a firewall, it could be ISP problems (not necessary problem but some rule that is blocking this).

      @ellyza,

      it seems you are behind a firewall.
      you have to contact your internet provider to open (or to tell you how to open) video streaming ports for you on your PC

      the firewall blocks your access to videos

    I seem to be having trouble accessing the old videos on the site. For example, I can access the new video format in F2 Lectures on “Inventory Control (part a) example 1, but cannot access the video on Process Costing: Joint Products (part a).

    I get “Server not found: rtmpt://r.acca.opentuitioncom.netdna-cdn.com:80/play”

    It was working an hour ago, I’m not sure what could have changed between then and now. Every other site seems to be fine.

    Thanks for the help in advance Admin.

      @nachibinga, you see it says: lost=0 (0% loss)

      so, the connection is fine, but you are behind a firewall,
      either your PC or your internet service provider firewall – so contact them to reslove this for you

      You see it says:
      Lost = 0 (0% loss)

      it means, connection to video server is fine,
      you should contact your internet provider to see what they can do to fix this error,
      maybe you are behind a firewall / maybe they have to open some internet ports…
