when I use the web interfac client with a real time display. It's verry slow and I have the error "503 Service Temporarily Unavailable".
I refresh the web page, but it repeat just after refresh.
best Regards; regards.
HTTP 503 error means the server hosting the web service is overloaded.
Is it under recommended spec?
Also, check Task Manager on the server for busy processes. Try restarting services - World Wiide Web Publishing Service , and Prognosis service, to see if they give some temporary relief.
