I shall do my best to help with this, so thanks for getting in touch.
I'd like to know exactly what problem you are getting and how it manifests itself? Is Skype failing to connect from the outset, and if so what error message is returned? If the failure is elsewhere please explain what steps preceded the error and what the error is.
I'd also like to know:
What version of Skype you have.
Your Operating System.
Whether you are connected via Ethernet or Wifi.
What security software is installed on your pc/laptop.
If more than one device has this same issue.
Hopefully your replies to the above will help me understand what may be causing the issue.
@RichardWhite321- really really sorry but we seem to have missed your post. If you are still having problems with this please post an update and we'll get back to you.
