The credential list which is need for scanning or to access the tool is not loadable.
Workaround
Move the file called credentialstore away from the Discovery folder.
Access the Discovery tool again and recreate the credentials.
- If you have a backup of the credentialstore file that used to work, you could restore it to the Discovery folder before accessing the Discovery tool again.
