I upgraded to FM 16 and on the client I keep getting a message that" FM Pro can't verify the identity of the IP number". When I view the certificate the first level says the certificate is valid. The second level down it says "this certificate is not valid (host name mismatch)". Initially, I was unable to export back in the key files from the CSStore folder I exported from the FM14 server as the instructions said to. I started the process from the beginning, and still was unable to upload. I called FM support (first guy I spoke to was great) they said I needed to re-key the certificate. So I made the request in FM then logged into GoDaddy and requested a rekey. It didn't work. I called FM support back w/case number - other guy not so patient - actually pretty condesending. Was told to go through the process all over again, which I did for a seond time. I am still getting the client message. The only difference I see is the certificate has the host name in all lower cases. The client sees everything in all upper case. Before I go down this rabbit hole again, does anyone know if the certificate setup in filemaker is syntax sensitive?
