Are you using a non-standard MTU size? This error indicates that a
write operation to the TAP driver is impossibly small, i.e. the packet
isn't even large enough to contain an ethernet header (for dev tap) or
IPv4 header (for dev tun).

Negatory. MTU is 1500:
MTU MediaSenseState Bytes In Bytes Out Interface
------ --------------- --------- --------- -------------
4294967295 1 0 23833 Loopback
Pseudo-Interface 1
1500 1 2450317296 362556326 Local Area Connection
1500 5 0 0 Local Area Connection 2
Also, I'm using the TUN device. Here's my config:
client
dev tun
proto tcp
remote <CENSORED>
resolv-retry infinite
nobind
persist-key
persist-tun
pkcs12 bkus1.p12
verb 3
ns-cert-type server
route-delay 30
route-method exe
The server grants the connection, an IP is assigned, but when traffic
tries to move, I keep seeing those errors and nothing gets communicated.
