Exception while publishing #35

I just had this error after launching a publisher:

The above exception was the direct cause of the following exception:

Don't know if it's just a transient thing as I did not see this error happen once in 4 days of tests - I could see a few frames reaching my client and then it crashed.

Thank you for reporting the issue.

I think I know the cause, and will try to update things to avoid it from happening again. It should be exceedingly rare though, as I only need to update the site's SSL certs every 400 days .. and that's what I think triggered that error.
