(letsencrypt) certificate invalid on Fortigate Firewall

Hello everybody!
Since 01.10.2021 both my nextcloud server as well as the official internet page are being blocked by fortigate firewall. The certificate is invalid. I presume this goes for every letsencrypt certificate.
Am I the only one having this issue?
Should I contact Fortigate rather?
Thank you in advance for replies.

I think you must delete the corresponding certificate. You can for testing only move it away.
Hopefully our Fortigate Firewall downloads the certificate again.
