After more digging, I am still stumped. Here is what I am seeing:
- A UDP port scanner shows that port 1194 is successfully being forwarded to the PI. So looks like my router is successfully forwarding port 1194. This is the port scanner for others wanting to check: https://pentest-tools.com/network-vulne ... nline-nmap
- In my client config file, if I change the IP address to the local static IP of my Raspberry PI on my home network, then I can connect successfully on my home network. Which tells me that a lot is working (openvpn server, keys, etc).
- But, if I leave my IP set to my external IP address of my home, then I am unable to connect from any network and here is the debug log viscosity on my mac shows [I substituted my real IP with XX.XXX.XXX.XXX]:

I have followed all the tips in this thread on how to configure the PI and have started fresh a few times to be sure I didn’t miss anything. I have tried from multiple clients (iPhone, Mac) from multiple networks.
Here is my openvpn config file for reference:
server 10.8.0.0 255.255.255.0
# server and remote endpoints
ifconfig 10.8.0.1 10.8.0.2
# Add route to Client routing table for the OpenVPN Server
push "route 10.8.0.1 255.255.255.255"
# Add route to Client routing table for the OPenVPN Subnet
push "route 10.8.0.0 255.255.255.0"
# your local subnet
push "route 10.0.1.201 255.255.255.0"
# Set your primary domain name server address to Google DNS 18.104.22.168
push "dhcp-option DNS 22.214.171.124"
# Override the Client default gateway by using 0.0.0.0/1 and
# 126.96.36.199/1 rather than 0.0.0.0/0. This has the benefit of
# overriding but not wiping out the original default gateway.
push "redirect-gateway def1"
keepalive 10 120
tls-auth /etc/openvpn/easy-rsa/keys/ta.key 0
status /var/log/openvpn-status.log 20

Any ideas would be much appreciated!
