We use Zapier to connect our WordPress and Salesforce systems. Through a Gravity Form on the website, an email is generated with a PDF file attached (through PDF Butler). For the past few days, the image in the PDF has not been loading. The URL is correctly loaded into Salesforce, but somehow the image cannot be imported in the PDF file.
This might be due to our SSL certificate having expired and then being renewed. The website was temporarily down during this process, and the issue seems to have started around that time.
Does anyone have any idea what might be causing this?
