Thank you for your post.
First, these are the type of problems that cause us headaches because we cannot reproduce the problem in house, and the problem can't be reproduced by you on a consistent basis and/or by performing specific steps.
Second, do you remember when you originally reported this? I'm having difficulty trying to find some instance of this behavior.
In any case, I have forwarded this information to our Development and Software Quality Assurance (Testing) departments for review. Knowing from past experience, they will ask me for your log files, so I have sent you a private message (top of this screen - right side - X Messages) with instructions where to send those files.
If you have any other information that you think is pertinent, please let me know, and I'll add it to the case.
I originally reported a number of years ago via the Report Problems web form that used to exist on the FileMaker site. I also posted to a number of listservs, and I do know at least a few people were also experiencing the same problem.
I do not have logs from any actual occurrences anymore at this point (they have expired from our backups). However, I have listed the applicable errors that are thrown when the issue occurs. I cannot reenable the SSL option on our production servers at this point unless you have a definitive testing/tracking procedure to try to do at the time of a failure (other than just tracking the log files) that will lead to a solution.
