Can´t connect to VPN

[Jodokus]

Hi everyone!

Since I am at a boarding school, I can´t connect anymore to my VPN... The provider of my VPN set my VPN up so that it should even work from my boarding school, but it somehow doesn´t.... anyways, here the log:

And here my .ovpn config:

proto tcp
remote XXXXXXXXXXX 443
resolv-retry infinite
nobind
persist-key
persist-tun
comp-lzo
ca nl2.crt
verb 3


I hope you can help me, thanks in advance!

the connection is reset after 21 seconds - without seeing the corresponding server log it is impossible to tell what is going on. There is, however, a fair chance that somebody at your boarding school decided to sniff out non-HTTPS traffic on port 443 and block it.
OpenVPN does not disguise itself from routers/firewalls.

I didn´t know that there are schools with a clever IT staff -.-.

Thanks for your answer, even if I hope it is not like you said...

Slow performance is one of the most difficult problems to troubleshoot.

[rastian]

Wow, this problem is new to me.......

[NickTrouw]

Last time I had similar problem. Another tips which might be useful : Disable any other network adapters on the machine that you are not using and try your connection again.

[dbonilla77]

contact your network host and ask them to give you an authentic password if you need one. I had a problem connecting to my VPN and I was successful by contacting the administrator.

Did NickTrouw suggestion work? sounds like something to troubleshoot.

Looks like this could be caused by a variety of different problems
