I am getting a "Not secure" when accessing my client's hosted 3CX site in Azure. It was fine a back in May before I shutdown the VM in Azure but I just turned it back on today and am getting the "Not secure" error.
@lan7 if the machine was powered off from May until now and you are using 3CX FQDN then yes the certificate will be expired because these renew automatically every 3 months.
Now, this will happen automatically on the background but if you don not want to wait until tonight, PM Me and I will send you instructions on how to force it now.
