We are looking into this.    In the meantime,  are you able to switch to IPsec and connect?

If your location is not blocking IPsec this should work.

 

Open the AT&T Global Network Client,  click on Setting and Login properties..  Under network services click on Configure and hit next until you get to Network.   In the dropdown box change from SSL to IPsec.

 

Please let me know.

 

Thank you.

Hello, the logs show something on this LAN Nework is blocking  your VPN Traffic.

 

Please provide the below link to the local IT Staff. Refer to Appendix C on all ports, IP etc...requirements to allow VPN Traffic to route properly.

Hello, it is possible your peer is on a different subnet at that location.  Please have the local IT staff ensure all the required IP's and Ports are opened (per the link provided) for the connection you are on to thier Network.  Can you confirm you can connect to AGNC at other locations such at your home broadband and/or WiFi hotspots?

 

Thank You

Hi AT & T Team,

 

I'm working at IBM and I could not connect to IBM Intranet network today via VPN.

 

The error is "Error 243 SSL protocol negotiation failed" even i changed to IPSec as I read from this website.

 

Kindly help to check my case, thank you very much. Attached file is the customer support file exported from my laptop for your reference.

 

Thanks in advanced,

Hai Nguyen.

Hi,

I've just successfully connected to IBM VPN network 5 minutes ago. No need to invest on this case any more.
