So I created a new customer on froxlor 2.2.4, debian bookworm and assign a new domain to this customer. Then I activate the letsencrypt certificate, which is generated in /root/acme.sh/new-domain.tld, but the certificate is not copied to /etc/ssl/froxlor-custom/*.key *.crt *.CA *.chain.pem, etc. The domain is not valid for ssl, cause the certificate is missing.

Any suggestions?

run the cronjob with --debug --force and check logs...i doubt the certificate got issued successfully, this works perfectly fine on a lot of machines here...
