Lync 2013 5.3.8932 app not working

[Uma Yellapragada]

We have started facing issues with latest Lync 2013 apk (5.3.8932) which was released on Jan 20th of this year.

Unable to Lync 2013 from Android mobiles, encountering errors as below.

We can't verify the certificate from the server. Please contact your support team
We can't connect to the server. Check your network connection and server address, and try again. Can't reach server
However we're still able to login using the old version 5.3. 8930. Is this a known issue and troubleshooting steps can be provided to resolve the issue?

Please note that we're using certificates from Internal CA .

Any suggestions?

Seems Microsoft released an updated version 5.5.3.8935 again on last Friday 20th Feb which fixed the issue. Now we’re able to login to Lync from android mobiles also.
Not sure what did they change.
