Unable to connect to AirVPN via SSL/stunnel on Android 8

Hi,

 

I just got AirVPN in order to circumvent the high level of VPN-censorship in my country. I want to connect via stunnel and tls-crypt to avoid deep packet inspection that is done so that I can use my VPN freely. I am having issues connecting to AirVPN via stunnel on Android. I have followed all the steps in the how-to guide and watched the guide video, but I am still unable to connect. I am not getting the "configuration successful" message in Termux like it shows in the guide video. Not very experienced so Im sure I've made some kind of a mistake somewhere, would be very grateful for any help.

 

Here is the Termux logs:

It gets stuck on "Waiting for server reply."

 

Here is the contents of the .ssl file:

# --------------------------------------------------------
# Air VPN | https://airvpn.org | Thursday 28th of June 2018 11:52:21 PM
# STunnel Client Configuration
# AirVPN_NL-Alblasserdam_Alshat_SSL-443
# --------------------------------------------------------

foreground = yes
pid = /data/data/com.termux/files/home/stunnel4.pid
client = yes
debug = 6

[openvpn]
accept = 127.0.0.1:1413
connect = 213.152.161.8:443
TIMEOUTclose = 0
verify = 3
CAfile = stunnel.crt

 

 

Could anyone please advise on how to go about fixing this? I've tried using other serves but all have the same issue.

 

Thank you!
