Unable to establish a connection to the specified secure gateway

herewego
Level 1
Level 1

When I attempt to connect, I get 2 error messages:

AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.

The secure gateway has rejected the connection attempt. A new connection attempt to the same or another secure gateway is needed, which requires re-authentication.

I have a feeling it's antivirus or a firewall or something because I also
had issues downloading the software. I tried to disable my firewall, but it
still is not working. This is my first time trying to connect.

Here is my log:

Check the ports are not being blocked. The range is anywhere between 20100 and 20354. However, this number will likely grow in the future.

 

Hope this helps.

So you try to connect from Home to your Office ?

 

Try different DSL connection if you can prove ISP not blocking ?
