FormCraft forms don’t submit to email address

FormCraft was very reliable and a good plugin until recently, now the forms will no longer submit, therefore not sending info to the email address, we use in the setting email.
It just stopped from one day to the other, no changes were made.
Using version Version 3.2.18 (free version) with WP 6.7.1
What can be the cause, using SSL, port 456, method is POST and also use Easy WP SMTP Version 2.9.0
The page I need help with is only one of the pages where the forms don’t work.
