My certificate has expired. I can't get into FM cloud to do anything about it. Why? Because my certificate has expired.
The solution (per Filemaker) is to go to FMCloud directly through the IP. This can be obtained in AWS.
This time the warning message on Windows Chrome does indeed include a "continue past warning" option, allowing you into FMCloud. You can then renew the certificate.
Some browsers will let you bypass the security warning. If you’re using Chrome, look for an "ADVANCED" button on the warning page.
I guess I didn't explicitly ask: how to renew certificate?
See FileMaker Cloud Help for step-by-step directions. The section on Managing SSL certificates should have the info you need.
