OpenVPN 3.0.2 (894) and iOS12 - not working

I'm running OpenVPN on a Ubuntu 18.04 LTS Server, Protocoll TCP on Port 443.
Connecting from a Windows Client works fine - connecting with my iOS12 Devices doesn't work.

I get the VPN indicator that it is connected to the vpn - but there is no traffic over the tunnel.
The problem started with upgrading the client app to 3.0.2.
Checking the logs, i couldn't see any errors oder indications, what causes the problem.

I'm runnung the openVPN Server now for years without a problem.

Any idea?

Regards Michael

This is probably related to "Disabled "Compression" by default (because it is insecure)" line in 3.0.2 changelog: https://itunes.apple.com/us/app/openvpn ... 79981?mt=8 (see "Version History")

The client has an option to enable/disable compression, but it doesn't help.

What helps is to disable compression in the server config. For me it was these two lines:

Code: Select all

# compress lz4-v2
# push "compress lz4-v2"

Things like VORACLE should probably be "Announcements" .. but who do we complain to ?

Is there going to be a fix for this? It's really annoying that my iOS devices no longer work because they can't support compression. I tried the compression setting in the app and as was noted here, it does nothing.

Thank you. Perhaps it's my misunderstanding of OpenVPN or how pivpn configures things - I also needed to update all my client configs which is slightly painful.

I have the same issue with my iPhone 6s on iOS 12.1.2 - No compression. Have tried enabling on the server (QNAP) and App. Still not working

Same cert,confgi, user and pass work perfecting on my old iPad - it uses the old app.

be great if this could be fixed.

I just noticed my OpenVPN connect wasn't working on iPhone where I have auto updates and 3.0.2. I can only NOT connect from my iPhone. Both my iPads and Mac and Linux computers connect flawlessly. Been using it for years and love it. My OpenVPN is set up on pfSense.

In the interim until this get straightened out I just made an IPSec VPN but make no mistake I'll go back to my OpenVPN server when this gets sorted out.

My IPsec config

I got it working by going into the client and enabling AES-CBC cipher algorithm on the ios open vpn client.

TO update: Still broken, no compression ever used and tried the above suggestions.

I have my OpenVPN server which is set up with compress lz4-v2.

I got stuck on this problem, too.

My solution was just setting the "Allow Compression (insecure)" from "NO (default)" to "FULL".
(The other settings are left as the defaults.)
