We have Zulu UC deployed and running on 18 desktop computers. We are using a SSL cert by sslforfree.
When we try to setup Android devices of some users we get the following error:
"Invalid Server Certificate"
"Zulu Mobile requires a trusted SSL Certificate to maintain a secure Connection. Your server’s certificate is invalid. Please contact your administrator and ask them to correct this issue"
This error is not present configuring IOS devices.
Please advice if the error is related to the provider of the certificate and purchasing a new SSL certificate let say from Sectigo will resolve the issue.
