Your problem
My problem is:
I get this error after I ran a campaign:update command in SSH.

Does this mean there was an error is sending emails? Because it seems it did send out all emails, right?

Hi,
to me this looks like SSL certificate error on the sending domain.

Check all your SSL certificates for all the domains involved are valid and did not expire.

I will check the SLL certificates.
