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.
