Nextcloud Fortigate Certificate Issue

Running newest version of NextCloud on unraid. This morning both my nextcloud server internet page is being blocked by fortigate. The certificate is invalid. NET::ERR_CERT_AUTHORITY_INVALID

Am I the only one having this issue?

Should I contact Fortigate rather?
