Hi Omar,
This issue typically occurs when the IBMid is already associated with an IBM Cloud account, but the registration or account-linking process didn't complete successfully.
A few things you can try:
- Sign in directly at https://cloud.ibm.com using the same IBMid instead of going through the registration flow.
- If you're unable to sign in, try using an incognito/private browser window or clear your browser's cache and cookies to rule out a session issue.
- If your IBMid belongs to your organization, check with your IBM Cloud account administrator to confirm your IBMid is still associated with the account and hasn't been removed or restricted.
- If the Next button remains disabled and you cannot access the account, the account association may need to be reset by IBM Support.
If none of the above resolves the issue, I'd recommend opening an IBM Cloud Support case. Include your IBMid (email address), screenshots of the error, and the approximate time the issue occurred. The support team can verify the backend account linkage and restore access if necessary.
Let us know if you're seeing this during account registration, invitation acceptance, or normal sign-in, as the troubleshooting steps can differ slightly.
