<p dir="auto">Other users don't experience this. I don't see any issues on the firewall itself. I'm really not sure what to check. My local network is behind a Cisco ASA 5505, so I thought maybe that was causing issues, but I can't see anything on that either.<br />
What else can I do to try and troubleshoot this issue? Thanks.</p>
<p dir="auto">Here's the OpenVPN config file:</p>

persist-tun
persist-key
proto udp
cipher AES-128-CBC
tls-client

remote &lt;redacted&gt; 1194
