@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.
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,
also, please send by email (ad***@*********on.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).
kindly outline for me the procedures for accessing the videos. becoz i’ve not accessed any. sxs
Using android 4.0 (ice cream) and getting a 404 error. It is saying that the link has changed. Any assistance would be appreciated.
Maybe JavaScript is not enabled?
Does your browser support mp4 or flash player?

@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

YOu are most likely behind a firewall. contact your internet provider for help. also see the support page: https://opentuition.com/support/
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.
It’s definitely a problem in my end because it seems to be working on the iphone on 3G, but I’m not sure why it stopped working all of a sudden on my PC.
Would be extremely grateful for any tips Admin.
try another browser,
if it worked for you before, it should work again
maybe it;s just temporary error,
