Hi,

I recently noticed strange issue with my ASA 5510 firewalls, which both work in active/standby mode. 

For some reasons I get the attached Login Banner popup window which doesn't allow to log in using ASDM, I can log in using SSH. The only fix so far is to reload firewalls in SSH. I haven't done any changes in the last few weeks and popup window appeared only today. During this issue I'm not able also to connect to VPN

Anyone with the similar problem or solution?

Thanks for your help
