The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Problem: Unable to Load CCM UI After an Upgrade
After the CCM upgrade, the UI does not load, and in v4.8.2+ just displays a grey screen.
In the /usr/local/cliqr/logs/managementserver.log file this error message is observed:
During the upgrade, the password that CloudCenter uses to access its postgres database is corrupted. This can be resolved as the installation wizard on the CCM (if in HA run on both CCM's) runs and the postgres password is re-entered.
Navigate to the DB Parameters tab and reenter the DB password.
If you do not know the DB password, contact Cisco TAC for the default password and then change it immediately.
