Error 113 (net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH): Unknown error in google chrome when connecting to Cisco ASDM


Looks like the default ssl encryption is set to des-sha1. 

Run the following to see what yours is set to:
#sh run | i ssl encryption. 

I was connecting my laptops ethernet port to the management port on the ASA.
My IP address settings were set to obtain. The ASA gave me an IP address. I connected to the ASA with the console cable to run the commands.


des has been broken for ages now. Looks like chrome won't connect unless you use a good encryption. I did the following to resolve:

#conf t
#ssl encryption aes128-sha1  (you can use higer if you want)
#wr mem

Now open chrome and go to https://192.168.1.1/admin
