I have updated the FOS at a Brocade 6505 SAN switch from 8.0.2c to 8.1.2a.
After this I cannot login to the management UI and always get the following message:
"Error:invalid session random"
I use the Java version 8 Update 161.
Has anybody an idea whats wrong here?
Clear the Java cache, and restart the Java session. That might do it.
