Does Set up OpenConnect VPN Server (ocserv) on Ubuntu 18.04/16.04 with Let’s Encrypt help?

Step 5: Fixing DTLS Handshake Failure

On Ubuntu 16.04 and Ubuntu 18.04, ocserv daemon ocserv.socket does not respect “listen-host” value from configuration file, which will cause the following error when clients connect to VPN server.

DTLS handshake failed: Resource temporarily unavailable, try again.
