We have Bordermanager 3.8.5 in a Netware 6 with SP5.
We have restricted access to you tube. We just allow go to youtube to users who are members of a specific group.
It has been working until now.
Recently most of the times people go to you tube they get the error
"An error occurred, please try again later" (yo can see that in the attached file). After that, If the user refresh the page 3 or 4 times then it loads the video. At the beggining we thought it was a youtube error but it just happens when we go througt the proxy server.

Any idea?
Thanks in advance.
