I am trying to get my computer to connect to an Adobe Connect server but I have had no luck. The error that Adobe is telling me is "ERROR: FMS Server did not return correctly!" and have done some narrowing down to figure out what the problem is...

  • I know that its not a router issue because it still doesnt work when I bypass it, also Adobe Connect works fine on all my other computers in my network
  • I have disabled the Windows Firewall (every which way) and that doesn't do anything
  • It is something to do with trying to connect to port 1935 on the server because I can connect to port 80 fine but not port 1935
  • I have a VirtualBox and Virtual PC network driver installed and I disabled those with no success
  • I had used a TCP optimizer and trying restoring the settings with no success
  • The furthest the connection to port 1935 will go in netstat is to SYN_SENT so for some reason the server isn't sending a ACK back
  • It doesn't work in Firefox, Chrome, or Internet Explorer (Yes, I made sure SSL and TLS are enabled)

I am wondering if this might be some sort of firewall problem but the thing is, I have Windows Firewall totally disabled and there are no other firewalls (that I know of) running. I thought this might be because I had Norton 360 installed but that wasn't the problem. Any ideas?

UPDATE:

Here is the traceroute and nmap scan from the computer that CAN connect:

I think you will see by comparing these scans that they are the same. I have no control over connect.bowvalleycollege.ca so whatever the problem is should be able to be fixed on my end.

When you say you disabled Windows Firewall, is that on your machine or on the machine hosting the Adobe Connect server? –  Colin 't Hart Sep 27 '12 at 7:21
    
Port 1935 is absolutely required since RTMP protocol uses it to send media. –  Dims Sep 27 '12 at 9:07
    
@Colin'tHart Its on my (the client) machine. I should also note that I don't have access to the server so I can't do much about that, however I am able to connect on my other machines so the servers not the problem. –  ub3rst4r Sep 27 '12 at 17:42
    
Can you tracert to the server from both a machine that can and can't connect and see if there's any difference? Also, can you run nmap against the server, again from both a machine that can and can't connect and see if there's any difference? I'm wondering if there's another firewall between you can the server that's behaving differently for you than for other clients? Are you in a different subnet perhaps? This can be the case in some organizations where network security is implemented depending on your role in the organization. –  Colin 't Hart Sep 28 '12 at 7:59
    
@Colin'tHart I have added the traceroute and nmap scans to the question above. –  ub3rst4r Sep 29 '12 at 18:35

After a few months of not being able to connect, I tried again one day to connect and it worked no problem. I'm guessing the problem was something to do with Adobe Connect because it was updated a few days before. I seem to recall trying to contact Adobe about this issue and they said it was something to do with my computer or network configuration.
