Hi there, 

 

i have a big problem with the airvpn client since yesterday. I have tried several times yesterday and today to connect to any of the servers (manuelly and automaticly), but it doesn´t word. The client flushes DNS, checks the route and then disconnects, restarts and starts the same steps again. I have no idea where the problem comes. The client worked on saturday perfect. I have read that some other peoples have similar problems too. I have disabled the TCP/IPv6 on the TAP adaptor (this was a solution suggested in the topic) but it doesnt word for me...

 

Please help me! What should i do?? Thanks in advance ;-)

 

This are the logfiles from the client:

Hello!

 

Please upgrade to client version 2.7 and try again.

 

If the problem persists, please try a connection in TCP. You can change connection mode in menu "AirVPN" -> "Preferences" -> "Protocols". Feel free to post the logs in TCP as well.

 

If the client keeps failing in UDP and/or TCP at "checking route" state, disable the check: in "AirVPN" -> "Preferences" -> "Advanced" un-tick "Check if the tunnel effectively works", click "Save" try again a connection, open a browser and browse to airvpn.org. Check whether the central bottom box is red or green.

 

Feel free to update the thread.

 

Kind regards

Hello, 

 

thank you for the quick reply on my topic! I have tried to test the client again this morning and it works again without doing any changes on the set up. Probably there was something wrong with the servers previous days or with my system. I don´t know but it works now and i am happy. 

 

Best regards
