Problem description
Admins are not able to login to SFDC 2.0 managed package and get the below error
Check the Developer tools and in the Console logs we see errors about Storage limit:
Resolution
To Fix this issue Follow the below steps:
In Salesforce go to Setup.
In the Quick Search window search for “Storage Usage”.
Here you would see the total storage allocated for your Salesforce instance
If the storage is utilized at 100%, then the login will fail, as we make an API call when logging to Managed Package and this call will create an Entry in Salesforce.
If there is no space available to create an entry, login will fail.
We can have additional storage added (by request)
