OpenSSL verify untrusted issue

I have One-Tier PKI, and I have self-signed CA (ca.crt) and host cert  
(host.crt). 

root@radius2:/tmp/certs# c_rehash ./ca-list/

root@radius2:/tmp/certs# tree
.
├── ca.crt
├── ca-list
│   ├── 577f4bb3.0 -> ca.crt
│   ├── ca.crt -> ../ca.crt
│   └── ed3eb11a.0 -> ca.crt
└── host.crt

I'm trying to verify certificate against CA, and it says "untrusted". 

root@radius2:/tmp/certs# openssl verify -verbose -crl_download -crl_check 
-show_chain -verify_depth 10 -issuer_checks -no_alt_chains -check_ss_sig 
-CAfile /tmp/certs/ca.crt -CApath /tmp/certs/ca-list /tmp/certs/host.crt
/tmp/certs/host.crt: OK
Chain:
depth=0: O = OD.FREEIPA.XYZ, CN = rpi4b.od.freeipa.xyz (untrusted)
depth=1: O = OD.FREEIPA.XYZ, CN = OD.FREEIPA.XYZ Certificate Authority

Could anyone explain why this shows "untrusted" and how to make it 
"trusted"?

root@radius2:/tmp/certs# openssl version
OpenSSL 3.0.14 4 Jun 2024 (Library: OpenSSL 3.0.14 4 Jun 2024)

root@radius2:/tmp/certs# ldd /usr/sbin/freeradius | grep libssl
        libssl.so.3 => /lib/x86_64-linux-gnu/libssl.so.3 
(0x00007f6665d2f000)

root@radius2:/tmp/certs# strings /lib/x86_64-linux-gnu/libssl.so.3  | grep 
OPENSSL_3
OPENSSL_3.0.0
OPENSSL_3.0.3

I have the same issue for FreeRADIUS running this server :
