Hi,
I recently had an error on the backend workflow part of our application.
One of our customers had this “workflow error” (See screenshot).
The error message is the following:
Workflow error - Temporary error connecting to Sendinblue - Send SMTP Template B (raw message: 520 Origin Error
520 Origin Error
cloudflare-nginx )
I have accelerated our domain with cloudlfare for 2 weeks and we have had no problems. What does the ‘‘cloudflare-nginx’’ error message mean ?
Is there someone who can help me with that? where did this mistake come from?
Thank you !!
Gabriel
