Brand Portal Login Error Messages
It is possible that you may encounter an error code when logging into the Brand Portal. Below is a list of the error codes that may appear and the what may be done to correct them.
501/USR: Incorrect username or password
A 501/USR error means the login credentials are incorrect — either the username (email) or password does not match any existing user in the Brand Portal system.
Step-by-step solution: For retailers or sales users, try the following:
Double-check credentials:
Ensure the email address is correct.
Passwords are case-sensitive — check for typos or extra spaces.
Use the self-service reset:
Go to the Brand Portal login page.
Click “Forgot password” and enter your email.
Follow the instructions in the reset email to set a new password.
For administrators, if the user cannot reset their password:
Reset via Backend Console:
Go to Users, find the user by email.
Open Company Access, then click Reset Password.
An email will be sent to the user with reset instructions.
Check user existence:
If the email is not found, confirm that the user exists in the system.
For ERP-synced users, ensure they have been synced and activated.
502/COL: Not authorized for collections of webstore
A 502/COL error when logging into the Brand Portal means the user is not authorized to access any collections. This usually happens when no collection permissions are assigned to the user.

Step-by-step solution: For administrators, take the following steps in the Backend Console:
Check the user’s collection permissions:
Go to Users in the backend.
Search for the user's email and click their name.
Under Collection Access, verify that the user has at least one collection assigned.
Assign access if missing:
Manually check the boxes next to the appropriate collections.
Click Store in the top-left to save changes.
Automatic syncing (if applicable):
If your setup uses automatic synchronization from ERP:
Confirm the user is present in the cloud cache.
Ensure
syncUsersFromCloudCacheis enabled in Collections > Advanced.Check that the user has a valid email and is of type
RETAILERorRETAILER_WEB.
503/CUS: User has no customers according to the collections it has access to
A 503/CUS error in the Brand Portal means the user has no customer assigned within the collections they can access. This typically affects retailer users who have been synced without proper customer linkage.

Step-by-step solution: For administrators, follow these steps in the Backend Console:
Check if the user is linked to a customer:
Go to Users, search for the user’s email, and open their profile.
Under Company Access, ensure a customer number is linked.
Verify customer data in the Cloud Cache:
Navigate to Collections > Advanced > View Collection Data.
Confirm that the customer exists in the Cloud Cache with a valid
customerNoandemail.
Ensure correct collection settings:
In Collections > Settings, check that:
syncUsersFromCloudCacheis enabled.minimalUserTypeForAccessis set appropriately (e.g.,RETAILERorRETAILER_WEB).
Manually activate or resync user (if needed):
If the user doesn’t appear in the user list, ask them to activate their account via the Brand Portal login screen.
To manually sync a user, click on
SYNC USERin the Temporary User Sync section of a selected user
504/SRV: A time-out has occurred, please try again.
A 504/SRV error indicates a timeout occurred during login. This typically means the Brand Portal could not retrieve data from the backend systems in time.
Step-by-step solution:
Retry after a few minutes:
Temporary network or server issues may resolve quickly. Retry logging in after waiting 2–5 minutes.
Check internet connection:
Ensure a stable internet connection. Switch to another network (WiFi or mobile) if possible.
Clear browser cache and cookies:
Cached data may cause issues. Try logging in using a private/incognito window.
Test with a different browser or device:
If the issue persists, try logging in on another browser or device to rule out local issues.
Admin check – Backend system status:
Administrators should verify if the Cloud Cache or ERP integrations are experiencing delays.
Go to Backend Console > Collections > Advanced > View Collection Data to confirm data is available.
