I've problem, my mobile clients using intermediate certificate for verification that stored on mobile.
- root : ISGR Root X1
- ca intermediate : X3 Authority
But after updating i got new root so new intermediate certificates.
- root : DST Root CA X3
- ca intermediate : R3
So my clients unable to verify domain.
What can i do to solve it without updating clients ?
Is it possible to generate new certificate chain using predefined CA Root like ISRG Root X1 ?
How can i do it with certbot ?
