Cisco ASDM gets stucked

[Zach_Sec]

Hi,

i encountered an unusual problem with the ASDM while logging into the ASA. I have 2 5515-X ASA's running 9.4.3 OS with ASDM 7.6.2 version. The problem is the ASDM shows the message "Getting updated software" and when it says "Software update completed", it gets stuck there. I tried almost everything, such as putting a new ASDM version on the active and the standby unit, reinstalling/installing older versions of java (currently using java 8), setting up java with recommended setting for ASDM (lower security and exceptions list), using 128-bit ciphers on the ASA but still nothing... Tested on Windows 7 x32 and Windows 10 x64. Does someone perhaps have any idea?

Best regards,

Zach

I have this problem too..but for me, it says "Contacting" and it never works. 

A workaround I found is that you can run perhaps "ASDM as Java Web start application". That worked for me..:)

Best Regards,

I forgot to mention that i'v tried that too, but still, it doesn't work :/.

What is the error?? if it is a java error then perhaps you should give the IP address as an exception in the exception list in Java.Go to Programme, Java and then in Security and then add the management IP address of your ASA firewall. for eg.

https://x.x.x.x

Did you try to downgrade to Java 7. I had similar problem which was fixed when downgraded to Java7

[Zach_Sec]

Tried that too, didn't work. I'v tried even with java 6, but nothing...

Any news on this topic ?

Stuck with same problem.

Any info about how to avoid this will be helpful.

[Zach_Sec]

It has been fixed in the recent ASDM version. Good luck :)
