Other bare metal systems and their results with the same PEM file:

Verifies on Proxmox (the one running the VM) with openssl 1.1.1n

Verifies on Ubuntu 22.04 with openssl 3.0.2

Fails on CentOS 7.5.1804 with openssl 1.0.2k-fips

Additional tests done with an identical PEM file and the results:

Passed on Ubuntu Server 22.04 VM, openssl 3.0.2, installed on the same 

proxmox host as the Alma VM that fails.

Passed on Ubuntu 22.04 desktop bare metal, openssl 3.0.2

Failed on Centos 7 VM running in qemu on that Ubuntu desktop, openssl 

1.0.2k-fips

Failed on Fedora35 VM running in qemu on that Ubuntu desktop, openssl 1.1.1q

Passed on Ubuntu Server 22.04 bare metal, using quictls openssl version 

3.0.5+quic

Looks like there is something about RPM-based distros that breaks part 

of openssl.

One other bit of info.  I ran another test on the Alma VM where I 

compiled the master branch of https://github.com/openssl/openssl to 

/usr/local/ossl3 and used that to try the verify. This is the failure 

output:

[root@certs ~]# /usr/local/bin/ossl verify -CAfile 

/etc/ssl/certs/local/DOMAIN.wildcards.pem 

/etc/ssl/certs/local/DOMAIN.wildcards.pem

C=US, O=Let's Encrypt, CN=R3

error 2 at 1 depth lookup: unable to get issuer certificate

error /etc/ssl/certs/local/DOMAIN.wildcards.pem: verification failed

[root@certs ~]# /usr/local/bin/ossl version

OpenSSL 3.1.0-dev  (Library: OpenSSL 3.1.0-dev )

Thoughts?

Thanks,

R3 is a lets encrypt intermediate cert. This could be due to the retirement of the ISRG X1 certificate last year. I would check that  /etc/ssl/certs or wherever the default ca store is on your systems, is up to date.
