During the installation, due to issue in my server network, acme was not downloaded from repository.
I solved the issue by doing following steps:
1. Install acme (with proxy)
[root@server ~]# sh /scripts/install_acme
--2022-10-01 19:45:48-- http://get.acme.sh/
Proxy request sent, awaiting response... 200 OK
