Systematic error in AddCertifiate function

[fkorsa]

On one of my app services, the AddCertificate function in the WebJobs fails consistently with the stack trace below. I can see however that the certificate for that website was correctly renewed, so it doesn't really matter that much to me; but the error may be a sign of something wrong in the code which you may want to investigate.

I have the same configuration (same application settings, app service plan, resource group) on a lot of other app services, so I have no idea what could be different on this one to cause that issue only there.

Same issue with my Azure WebApp. Changes in Azure, maybe? Subscribing for updates!

I am seeing this issue on only one of my webapps on version 1.0.5.

[zhangpengchen]

i had the same issue with the latest version, haven't figured out why
