The issue you are facing:
I extended the SSL certificat with certbot -d old.domain new.domain.
now https connections to old.domain are not working. website shows broken files and folders section. basically showing no formating at all. seems like no css is loaded at all.
It works on old.domain with http. and on http and https with all other trusted domains (new.domain, local ip, local alias)
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Login in on https://old.domain
- broken files and folder view
- https://new.domain all works as expected
