[Resolved] NETWORK_EOF_ERROR (transport error)

Post by hey_aj » Sat Aug 26, 2017 11:25 am

Have been using OpenVPN on 3 different iOS devices for weeks without issues. Yesterday, all 3 encountered the same issue- my iPad and iPhone here on business travel in Australia, my wife's iPhone back home in the US. Doesn't matter if on cell data or wifi. Key problem seems to be a transport error per the log below. Client status toggles between "waiting for server" and "transport pause" before timing out. Had wife reboot our asus router but did not resolve. Grateful for any assistance.

Check your server log.

Sure, two follow-up questions:
1) I assume you are referring to the log on my router, in which case I will need to check when I return home as I am currently remote
2) Any suggestion as to what I am looking for or what the issue is? Or, just generic guidance to check the log?

Thanks

You need to verify that a connection attempt was made and what went wrong.

Did you verify the connection attempt was made?

Re: NETWORK_EOF_ERROR (transport error) SOLVED

Finally home from travels and could log into my router (ASUS RT-ACRH13). On OpenVPN Server config page there was this message: "OpenVPN server daemon failed to start". Tried various things to restart it, including reboot. No obvious way to do this. Then noticed alert for a firmware upgrade. Did the upgrade. All good now.
