Not sure exactly when it started, but the frequency has become daily now. Each day, at around 10:15pm CST to around 12:15 CST, I can't connect to the server. Sometimes the issue lasts longer, sometimes shorter. When trying to connect, error message is just Failed to connect to the server Timed Out. I have also tried connecting via console client, which the error message received there is, Unknown or not supported MC version '1.10.2', followed by Failed to ping this IP. I can ping server fine via cmd, but it times out when looking at server list in MC client. I have tried other versions of 1.10, I have reinstalled MC. I have tried connecting on multiple computers, as well as fresh VMs and receive the same errors. I have disabled firewalls, anti-viruses, bypassed routers, reinstalled java, uninstalled all mods, tried new OS install on VM. When looking online I have only found issues pointing to server side problems, but nothing specific to narrow it down to. The best I can do is offer a time, which is approx. 10pm CST to 12pm CST, now occurring daily. Any help is appreciated, thanks.
Edit: also forgot to mention I can connect to all other servers, but not p.nerd.nu, and have even tried c.nerd.nu with same effect.
