OK, I understand now what the problem was. Quite a while ago I added a line into the /etc/hosts to fix a temp DNS issue and completely forgot about it. So while DNS server was correctly resolving tools.usps.com to 152.195.33.23, my previous /etc/hosts entry was overriding it to 23.217.162.158 which was causing the certificate issue.
And this is why putting stuff into /etc/hosts is basically never the right answer. :)
