Hii I have a problem when log in skype for business, the error code kb2566790
I have tried this troubleshoot on this link (https://docs.microsoft.com/en-us/SkypeForBusiness/troubleshoot/online-configuration/dns-configuratio...), add SRV record and CNAME record on my DNS server but still cannot log in SFB. But when I change my computer with DNS google 220.127.116.11 I can log in. It seems like my DNS has a problem. Can someone help me with this? I really appreciate someone helps me with this.
i have read this post that similar to my problem https://techcommunity.microsoft.com/t5/skype-for-business-server-2019/skype-for-business-2019-on-pre... but I don't really understand it.
