Why is the portal so slow despite a fast internet connection?

This problems may occur on different PCs with different configurations. Is there a measure to speed it up?

Performance problems can be caused by different browser and/or antivirus/firewall configurations.

To carry out your own fault diagnosis as quickly as possible, you can take the following steps:

  • Deactivate browser add-ons, such as Adblock Plus
  • Clear the browser cache and cookies and restart the browser
  • Use another browser or even another PC to observe and compare the behaviour of the ITscope Online Platform there
  • Check your antivirus and firewall software settings, e.g. deactivate them briefly and test the speed of the portal without active antivirus or firewall software
  • In addition, check for possible problems with WebSockets using a WebSocket test that you can run under the following address: websocketstest.com
  • Allow the following IP ranges, for port 443 (https):

    85.115.14.84   to   85.115.14.86  (85.115.14.80/29)
    and
    213.144.1.132  to   213.144.1.135  (213.144.1.132/30)
    and
    212.60.201.184   to   212.60.201.187
  • Domain names that must also be allowed include the following:

    www.itscope.com
    media.itscope.com
    api.itscope.com


If performance problems persist after carrying out these steps, you can also send us the link to the WebSockets Result-ID (which you will find at the bottom of the websocketstest.com page), as well as a detailed error description, to support@itscope.com in order to allow us to investigate possible sources of error.

Do not forget to also send us a screenshot of the portal settings.

To do this, click on your profile picture in the top right-hand corner, and then select the ‘About‘ menu item (see screenshot below).
