Stopped working

Hi, what has changed in your site or server before this issue started happening in your site?

Thank you

Nothing could affect anything changed before it but I reversed the small changes but no result. (i had a Cronjob about posting to social media, I canceled it, yet it is still the same. tried many solutions, tried other plugins, it stopped for any email other than APIs. Sendinblue api is working, but they don’t sign the email domain, it has deliverability issues for my package. I want to be able to use Namecheap email again (privateemail.com).

log in Cpanel:
Could not open socket

I was using Namecheap email servers. They work fine on everything. I called them, nothing blocked on their side. My hosting also says nothing wrong on the domain and website hosting side.

I am using bunny CDN, w3cache, and Cloudflare DNS.

What happens if you disable our plugin? Then carry out a test. Let me know what happens.

Thank you

So your email deliveries in your site works without the use of our plugin. Is this correct?
