Seeing this while doing a Network Upgrade
Warning! Problem updating https://domain.tld/blogname. Your server may not be able to connect to sites running on it. Error message: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
The site is entirely SSL only and using a self-signed certificate.
Any ideas to fix ?
