I got a customer that was very helpful with troubleshooting. This is what we got:
-------------
1. nslookup wyday.com
-------------
Server: dns.opendns.com
Address: 208.67.222.222
Non-authoritative answer:
Name: wyday.com
Addresses: 2606:4700:`0::ac43:20b2
2606:4700:`0::6814:3f62
2606:4700:`0::6814:4062
172.67.32.178
104.20.63.98
104.20.64.98
-------------
2. Tracert wyday.com
-------------
Unable to resolve target system name wyday.com
3. Wyday.com does not open in Internet Explorer on Windows 10 Pro
4. Regedit entries for TLS 1.2 did not help
4. No AV, VPN, or Firewall
5. Windows Defender running. After turning it off, still no connection to wyday.com
What else can we try short of Wireshark?
