OpenVPN log question

[JDE100]

I recently setup an RT-AX88U with Merlin firmware and an OpenVPN server. Everything seems to work okay. I noticed the following in the logs and wondering if this is some type of attack? I do not recognize any of these IPs

If you use a commonly used port, then you will get random connection attempts hitting it. They aren`t attacking you, they are just scanning random IP addresses, looking for a vulnerable target.
