Most common questions used to investigate
Is the application not turning on?
Are you not able to login into your account?
Are you not able to contact someone through Skype?
Is your application having trouble locating either your microphone, speaker or webcam?
Is the video quality or the sound quality really bad during a call?
Are you not able to put credits into your Skype account?
Did your Skype credits vanish after some time without making any landline calls?
Are you not able to join a meeting through a link/code?
Common conclusions
Check if the application was installed properly and the version which you installed is a stable version. If not, re-install the application.
First check the credentials you have entered are correct. If not, enter the correct login details and try again. If yes, check your internet connection and try again after making sure it is working.
Check your internet connection and make sure it is working. If it is and Skype is still not working, make sure your device is not using any type of VPN service.
The problem might be with the application. Go to the settings and devices option and make sure the correct mic/speaker are selected as the output devices. As for when the webcam is not detected, a simple restart of the whole computer will do the job some times.
The problem most likely is with your internet connection. Make sure it is working and place your device where the signal strength is above average.
Check if you have put your bank details correctly and make sure your card has been activated. If the problem persists, contact your bank as they may be withholding the payment as a security measure.
This might happen after a total of 180 days of no calls to local/landline numbers. To view the credits simply click on "Reactivate Credits" option or manually reactivate them by going to settings and credits.
First check if the internet connection is stable and the link is authentic. If both are good, the link might have been corrupted as sometimes this happens. Simply create a new link or ask the host to send another link.
For any further problems contact the skype online helpline and they will guide you on how to fix the problem.
