I am having an issue with SSL cert cacheing on a certain subdomain that I use for development.
The browser is looking for the expired root LetsEncrypt certificate, DST Root CA X3, which expired in Sept 2021.
My browser caches are clear, and this certificate does not exist in my Keychain. The newer ISRG Root X1 certificate does exist in my keychain.
I believe this is a Mac OS cacheing issue, but I do not know how to clear it (without upgrading the OS, which I cannot do right now).
Please could you advise.
