HAProxy certificate issuing error

[netech]

pfsense+ v23.05.01
HAProxy v0.63_01

After the latest update I can no longer assign an ACME certificate to a HAProxy Frontend, not matter which certificate it is. Error generated is:
Errors found while starting haproxy
[NOTICE] (86157) : haproxy version is 2.7.6-4dadaaa
[NOTICE] (86157) : path to executable is /usr/local/sbin/haproxy

The certificate is indeed in the folder /var/etc/haproxy_test/HTTPS_Frontend/HTTPS_netch.au_633b5acc820cd.pem and the certificate looks valid. I do not understand what /var/etc/haproxy_test/ is compared with the other folder /var/etc/haproxy/
