Some of my sites give a browser security warning ERR_CERT_AUTHORITY_INVALID.
In these cases the Common Name in the certificate is listed as the server domain not the actual site domain, i.e. servername.default.name.uk0.bigv.io instead of mysitename.com (according to certificate viewer in browser).
I have multiple sites on Symbiosis. Some of them load fine without errors or warnings, and for these each certificate has the correct Common Name mysitename.com
How can I fix the problem for the affected sites please?
There is mention of a similar problem on this forum but I've combed that and mine has not resolved itself overnight.
Let's Encrypt itself seems to be working fine on all of them. It might be an Apache issue or related to ownership/permissions but I don't know.
I am happy to paste logs/config files in here if that helps.
Thanks in advance for any help.
