Client cannot download updates from WSUS, clientdiag error

Hello,
I have a problem with WSUS and computer, which connects to WSUS from internet.
Client succesfuly reports status to WSUS (strange that it does not show up in tergergroup, but in the unnassigned folder), but he cannot download updates.

ClientDiag.exe shows error in the end, maybe someone could help me:

server is dedicated to WSUS and do not have apache or any other software. It runs on port 80, but I have redirected 8530 port from internet to 80 port on inside server. As I mentioned, client apears in WSUS, it reports correct status of updates.
As client use WSUS from internet (outside our LAN), I can not check connection both ways. Telnet from client to server connects.

I think your issue is with the port redirection, did you try changing the clients to just point to http://wsus.myserver.lt   <<<without the 8530


If WSUS is installed on port 80, clients also need to point to port 80  and vice versa

It is OK to forward 8530 port to internal 80 - it works. Solved half of my problem when found error in script, whith I use to configure client to use WSUS - now cliendiag does not show up any errors.
The only thing is not working now - client does not take place in WSUS computer group (targetgroup configuration entry). It is still "unassigned"...
