Looks like it was the CA expiring that did it:

walt@work:~/git/gravity/assets/certs$ openssl x509 -noout -dates -in ca.pem                             
notBefore=Jul  9 20:17:00 2017 GMT
notAfter=Jul  8 20:17:00 2022 GMT
walt@work:~/git/gravity/assets/certs$ ls *.pem |  xargs -n1 openssl x509 -noout -enddate -in 2>/dev/null
