Problem with connecting to ASA with ASDM after upgrading

[j.smith@sepidarsystem.com]

Hello,

We have a problem with connecting to ASA through ASDM. Before we were using ASA 9.9 and ASDM 7.92-152 and everything was good but after upgrading to ASA 9.12(1) and ASDM 7.12(1), it seems only 2 of us can launch ASDM and as soon as the third one makes a connection, automatically makes the first user disconnected from ASDM. I have tried changing "Management Session Quota" and set them to maximum values. But the problem did not go away. I was wondering if you could help me with this problem. Can anything be related to Cisco deprecating and removing tlsv1 and such things in new versions of ASA?

Thanks

It seems like a bug on  ASDM 7.12(1). Please do not upgrade to this version. you will be in big trouble. I am downgrading to 9.8.4.
