Displays the SPAM Error (Yellow Border) even though messages are genuine

Hi there.
The comment spam checking is disabled.
WP SMTP from WPForms is installed.

Can send messages from other Form plugins.

But CF7 forms, new or old, keeps showing the Yellow Border error regardless. I’ve checked with the server administrator, there are no configuration errors (as seen from the success of other plugins).

I cant find anything that can cause this. Any help is appreciated. Link is provided with the Topic.

Edit:
Server config: Nginx, ISPConfig 3.
