Yesterday I upgraded my FileMaker Server from 15 to 16. All went well including buying and installing a GoDaddy Standard SSL. It worked just fine and the clients showed the green icon and (in 16) could click on it and see the cert is valid, etc. I tried 15 and 16 FMP/A's and all worked fine, so I was quite happy. Then today, the clients are getting this SSL warning. Note that it says the SSL is invalid and can't be verified. However, if you click on the "View Certificate", then it shows that "This certificate is valid". See below where I've connected from the remote desktop Launch Center.
Is it possible that the cert didn't load the full chain or FileMaker chose to not trust GoDaddy root? Any suggestions?
