Cannot connect to ASA using https

Fernando Patzlaff — Mon, 11 Mar 2019 17:35:06 GMT

I'm trying to access my box ASA 5540 by https://ipaddress but I can't. I'm using Linux. I already have installed ASDM (when it works) and I can enter in the box by ASDM.

The Mozilla show the message: "Error code: ssl_error_no_cypher_overlap".

But I was looking and I did these tests.

OS	Internet Explorer 7 and 8	Mozilla Firefox 3.6	Google Chrome
Linux	doesn't work	doesn't work	doesn't work
Windows XP	Works Fine	doesn't work	Works Fine
Windows Vista / Windows 7	doesn't work	doesn't work	doesn't work

I've already clear all configuration of browsers, reboot the box, reboot the machines, re-generate a crypto key on ASA, enable and disable the http server and didn't work.

st02/sec/act# sh run http
http server enable
http 192.168.1.0 255.255.255.0 management
http 0.0.0.0 0.0.0.0 external

st02/sec/act# sh run asdm
asdm image disk0:/asdm-625.bin
asdm history enable

Looking to ASA log it possible see:

6|Apr 20 2010|14:01:19|725001|192.168.100.100|35539|||Starting SSL handshake with client external:172.28.7.94/35539 for TLSv1 session.

Can anyone help with this situation.

Check the output of: sh run all ssl

Make sure you have all the combinations of ssl encryption algorithm as per the following:

ssl encryption 3des-sha1 des-sha1 rc4-md5 aes128-sha1 aes256-sha1

the command

ssl encryption 3des-sha1 des-sha1 rc4-md5 aes128-sha1 aes256-sha1

solve the problem. Thanks!
