Getting “insecure connection” message when trying to subscribe to a calender

Hi nori-lynn,

Have you tried to do this from a different Wi-Fi network to see if the issue persists? Have you contacted your work to make sure the link is still valid and there are no issues? Is your iPhone completely up-to-date? You can learn how to update your device here: Update your iPhone, iPad, or iPod touch

These questions will help us isolate your issue. We look forward to hearing back from you.

Take care.

nori-lynn,

If you go to Settings > Wi-Fi, do you see a message about the security of your network there?

If your Apple device shows a privacy warning or weak-security warning about a Wi-Fi network, that network could expose information about your device.

Have a look at this link for more information: Recommended settings for Wi-Fi routers and access points

Are you having issues accessing any other online content, such as viewing websites in Safari?

Thanks!

Thanks for the reply,

Have you had a chance to reach out to your work email provider? If not, they might have more information regarding the calendar provided through the work email account.

If this persists, Contact Apple Support for next steps.

All the best.
