Thank you for your post.
Are you getting any kind of error message? Are you sure you are installed on an Admin account? Are you able to launch FileMaker Pro (without a file)? If so, what happens after you select "Open Remote" from the File menu?
Any additional information would help me determine possible causes.
I found the solution at
Invalid SSL certificates created when FileMaker Pro is installed on or after Sept. 22, 2008
The server.pem file is a certificate that is created upon installation of FileMaker Pro and FileMaker Server. This file holds a 'Not Before' and 'Not After' timestamp with 9,999 days as the mark between them. In some cases, the FileMaker Pro installations on or after September 22, 2008 are generating server.pem files that did not adhere to the 9,999 day mark. The result is a 'bad' server.pem file which causes an issue with FileMaker Server and SSL.
At this time, the best options for a resolution are:
- Deactivate FileMaker Pro if applicable (select Help > Deactivate) and un-install FileMaker Pro.
- Set the client machine system clock to a time prior to September 22, 2008.
- Re-install FileMaker Pro.
- Set the client machine system clock to the current time.
