Hello,
I have berocket setup on my site to send automated sales report emails to me. I noticed a couple of days ago it stopped working. There’s also another WP site that I manage that’s using WP Mail SMTP as well. However, everything seems to be in working order and can contact and authenticate with the same credentials to the same SMTP server. I see that the DST Root CA X3 cert expired at the end of last month. Which is when I first started to notice the issue. However, I’ve since corrected this and have updated the CA certificate information on the host in question. The certs on the server with the issue and the mail server seem to be valid. I’ve ran out of ideas and places to look for what is causing this issue. I’m hoping someone can point me in the right direction.
