Cisco ASDM: cannot access due to certificate error

[RFC_2549]

Hello,

we have a Cisco ASA witch ASDM but seems to be a certificate issue. The certificate is using SHA256, is self signed but Java is saying that there is an issue with SHA1 since the error is saying "denyAfter constraint check failed: SHA1 used with Constraint date: Tue Jan 01 01:00:00 CET 2019". The problem arised only in the last period, is there a way to fix this error? The certificate is still valid

Thank You

Hello @RFC_2549 ,

What version of ASDM and java you have? 

Also can you share the output of : 
sh crypto key mypubkey rsa | i Key
sh run cry ca trustpoint
sh run ssl
sh clock

Regards!

What version of Java are you running. Some options you could try:

1. connect to the ASA using a web browser, then when the certificate error appears opt to install the certificate.
2. run the ASDM in the browser (webstart).
3. if not done already, update Java
