I've been having this issue for quite some time as well, and have been working with a Microsoft Skype for Business (SfB) support engineer on it. To be certain it's the same, or similar-enough issue, here's the setup I've been working with (or against it seems):
Need to make an urgent call and don't have time to work through these steps? On desktop you can use Skype for Web now without having to install anything, and then come back to these steps later. Launch Skype for Web on desktop now.

- To resolve this problem, we go back to the Certificate Wizard within the Deployment Wizard and select the three checkboxes under 'Default certificate' and click 'Request' as shown below: This will bring up the Certificate Request page where w need to fill in the relevant details as well as select one or all of the SIP domains which we want a SAN entry for.

* Corporate domain is on Azure AD (Active Directory)
* When signing in with the AD account, you are either a) Given a choice between 'Work or school account' or 'Personal account), b) usually automatically redirected to the company branded signon page.
If that matches up, the next step is to check the certificate which is on domain's federation services (ADFS) host. Gotan project la revancha del tango album torrent. This may require getting IT involved to find it, or reviewing the SfB logs.
When you get the host name, for example, 'adfs.mycompany.com', go to that address via HTTPS in Safari. So you'd go to 'https://adfs.mycompany.com'. Once there, click on the lock to the left of the address in the address bar and click the 'Show Certificate' button. Make sure that the selected certificate, in the tree view at the top, is the bottom-most one. The bottom pane should show some brief certificate info (Issued by, Expires, 'This certificate is valid' type message, etc.). Expand the 'Details' section in that lower pane, and look for the 'Signature Algorithm' line, which should be, roughly, the 12th one down. If on that line, you have something similar to 'SHA-512 with RSA Encryption' (forget about the long number afterward), then that is the source of the issue with logging on, and also, activating Office 365 (if you have a company account for it).

Starwind license keygen. OS X prior to 10.12 (Sierra) does not *natively* support 512 bit certificate signatures. So while browsers and everything else shows that, yes, the certificate is good, valid, unexpired, etc, the low level network stack in OSX, which is used by SfB to initially connect, does not, so it cannot validate that the certificate is valid, thus causing this issue.
Unfortunately, at this time, there doesn't appear to be a way to wedge in support for 512 algorithms in OSX, and that includes forcibly upgrading/linking openssl. The only way I've found to date, to use SfB on anything less than 10.12.x, is to essentially MITM yourself, using a proxy application, such as Charles, which will create its own fake certificate which you must trust, to connect.
