TLS server certificates must have a validity period of 825 days or fewer (as expressed in the NotBefore and NotAfter fields of the certificate). Connections to TLS servers violating these new requirements will fail and may cause network failures, apps to fail, and websites to.
Jan 29, 2019 Note: in real life not all mentioned steps are conducted by the Skype for Business client. So as you see in the video, the Skype4b client is designed to search for the frontend pool using pre-coded DNS records, it gets the domain name from the user’s sip-address one in red (user@ sip-domain) then start adding to it pre-coded values in the following order.

Nov 08, 2019 Question: Q: After upgrading to Catalina, Skype-for-Business-for-Mac fails with cert problem Hi. I was running nicely on Mojave (10.14) with Skype for Business for Mac, for almost a year, with no problems.
Although Skype offers to set the correct date and time too, in fact, the error can occur for two different reasons: - Incorrect date and time settings
To set the correct date and time on the computer:- Open the “Control Panel” of the computer.
- Switch to Classic View (i.e., the icons view).
- Open the “Date & Time”, put the correct time zone and enable “Automatically adjust clock for Daylight Saving Time”.
- After this, open the tab “Internet Time” (if you have Windows 7, click “Change settings”).
- Enable the option “Automatically synchronize with an Internet time server”.
- Select “time.windows.com” server and click “Update now”.
- As a result, after a few seconds the inscription “Time was successfully synchronized 15/10/2016 at 22:46 from time.windows.com” must appear.
- Restart Skype and check if the error has disappeared.
- Problems of Root Certificates
As a rule, if you haven’t set the latest root certificates, the error “Content is blocked because it is not signed by a valid security certificate” also can appear on Skype. To solve the error:- Download the file rootsupd.exe
- Run the installer of root certificates (if something went wrong, see below how to install root certificates manually).
- Restart Skype and check if the error has disappeared.
If the instruction has helped you to solve the error, write in the comments, it is desirable to specify the Skype version and operating system, in order to know exactly, for what computers this manual is suitable. Of course, any advice to improve this article is welcomed.
How to install root certificates manually
- Save the file rootsupd.exe (the main thing, not on the system drive). For example, I have saved it on the E: drive in the folder Roots. The full path is E:roots, and this is the way used in the following commands (if necessary, change the E:roots for the desired way).
- Run command prompt with administrator privileges
- Execute the following commands (copy them one by one and press Enter):
cd /d E:roots
rootsupd.exe /c /t:E:roots
updroots.exe authroots.sst
updroots.exe updroots.sst
updroots.exe -l roots.sst
updroots.exe -d delroots.sst
Attention!
If you have failed to correct the error with the help of these instructions:- In Internet Explorer, open the page Check access to Skype.
- Click “Check” and after the test is completed, copy the link to the result.
- Leave a comment on this page, with the link and the version of Skype.
Hi.
I was running nicely on Mojave (10.14) with Skype for Business for Mac, for almost a year, with no problems.
After I upgraded to Catalina (10.15), I am not able to log in. The SfBfM application runs.
However, after entering my credentials (yes, they are correct), I get an error message:
'There was a problem verifying the certificate server. Check your device's clock setting, or contact your support team.'
I have removed the SfBfM-related files from ~/Library, reinstalled Skype and (what I think are the proper) certificates for our server. No joy.
Any thoughts?
