I don't know what happend but I can't connect to AirVPN on my windows pc anymore.
"Checking Route" and "Checking DNS" always fails after 3rd try.

See the log: https://pastebin.com/cnVt8zCw

 

Hope you can help me out. Linux is working perfectly fine.

Hello!

 

This has been covered many times. You can go to Eddie's settings and uncheck "check if tunnel effectively works" under Advanced and "Check AirVPN DNS" under DNS.

I already knew that, but what's the reason the problem? I mean these options are quite useless then.

 

EDIT: Once I am connected with the settings you mentioned, the internet stops working. But ping in cmd works fine.

The same now happens on my linux system and with your settings the internet isn't working as well.
Which means: I can't use my vpn account at all.

You can try disabling IPv6.

I just discovered that connection is successful on both my linux (vm) and windows system when connected to my university network using wifi.

What could be the issue in my home network that is causing the problems? Hope you guys got any ideas for me.

I am using 1 main router and 2 APs. My pc is mostly connected via cable, sometimes with wifi.

Had the same issue, answer 1 from LZ1 to uncheck "Check AirVPN DNS" did the job, thank you!

Did you try to select "TCP on port 443" in Preferences -> Protocols, instead of "automatic" ?

I thought I already tried that. But seems like my ISP (Deutsche Telekom AG) blocks UDP connections.

I also figured out that if I disable the LTE on my router and only use DSL (I have a dsl hybrid connection), even UDP connections work just fine!

 

So it seems they only filter OpenVPN UDP connections on their DSL-LTE bonding servers.

To bad that TCP is way slower than UDP.

Hi, this happens to me sometimes on Win10.

Here's how I fix it:

 

Control Panel

Network and Internet> Network and Sharing Center>Change Adapter Settings

Right Click on “Ethernet”

Click “properties”

Internet Protocol Version 4 > Properties

Click "use the following DNS server addresses"

Preferred DNS server—208.67.222.222

Alternate DNS Server – 208.67.220.220

Thanks for the hint. But I am already using another open DNS server and like I said before: for me it has nothing to do with DNS problems. I can ping fine, even when being connected with route and dns check off, whilst having "no internet". This is simply due to the fact that my ISP filters the OpenVPN UDP traffic.
