On RHEL/CentOS, there are SELinux rules to prevent non-root users from using ping correctly. Try temporarily turning off SELiinux with `sudo setenforce 0`. Alternatively, you may be missing additional dependencies. I have an Ansible role I have created for installing Wine and the suggested/recommended dependencies. You can find the full list of dependencies that are recommended to install in the "wine_dependencies" YAML dictionary here. If you are familiar with Ansible automation and git, you can use the role from that "extra_dependencies" branch to install Wine. Although unlikely, it could be a packaging issue. The EPEL package was set to use Wine 1.8 (from 2016!) for the longest time and only recently got updated to 4.0. It does not exactly align with the newer/upstream Fedora packages (which is unlike most EPEL packages) that are tested since that distribution uses wine-staging instead of wine-stable. Let us know if you find a solution that works. Good luck!

Sincerely,
