Skype for Business doesn´t work for me. I can´t login

Question

Hello!

I can´t log into Skype. I always get this error-message.

The english translation is "No Skype for Business server could be found for reqcon.se with Skype for Business. There may be a problem with the DNS configuration for the domain. More information is available in KB2566790. Contact the system administrator."

I have an Office-license, so I don´t understand this error.

I have also fixed the DNS-configurations for both SRV and CNAME, but I still have troubleshooting. There´s something wrong with lyncdiscover. In English it is:

Connection test failed
