About a week ago my email cert expired. I know this because my Mail app on my iPhone stopped fetching new mail and brings up a Cert expired alert. This also stopped my n8n instance from sending emails. I've since manually renewed all my certs and using a 3rd party SSL checker verified that it now is valid for another few months. However, my iPhone is still showing invalid cert and same with my n8n instance.
Do I need to reset the cache on these channels somehow? Is my email cert actually still invalid?
