A Claude Code 403 or Request not allowed message does not, on its own, prove that your account is banned. First identify when the error appears and which service received the request. Installation downloads, subscription sessions, direct API calls, and company gateways do not share one universal fix.
Do not begin by deleting your configuration or renting another computer. Keep the original error and classify it.
Find the failing step
An HTML error page from a download or proxy is different evidence from a structured API error. Record which one you received. Do not assume that a third-party service uses Anthropic's status codes identically.
Confirm the account and request route
Inside Claude Code, inspect:
Check the identity and provider information available there. A browser signed into one account is not sufficient evidence that the running CLI uses it.
Then compare the intended setup with what actually runs: subscription login, an API key, or an organization-managed route. If a key or endpoint was configured for a previous project, do not remove it blindly—first establish who owns it and what depends on it.
The subscription and API billing guide helps separate those routes. If the actual message is about an expired login rather than forbidden access, use the login-expiration walkthrough.
Apply the fix to the relevant branch
For a post-login 403 Request not allowed, Anthropic's installation and login troubleshooting page directs subscription users to check plan status, Console users to check their Claude Code or Developer role, and proxy users to check network configuration.
For a direct API response, the API error reference distinguishes an authentication failure from a permission failure. A valid key can still lack access to the requested resource. Ask an authorized administrator to check the relevant organization and workspace rather than granting broad permissions as an experiment.
For a gateway, keep its approved configuration and use its own support route. Changing to a personal account may create a billing or data-handling problem without fixing the original issue.
An explicit suspension is a different branch: use the account-suspension guide. An identity-verification request likewise needs its own official process. Neither is resolved merely by moving the same credentials onto a US computer.
Retest one thing and keep useful evidence
After making one justified correction, repeat the smallest request that previously failed. Avoid running a batch of expensive tasks to check access.
A useful support report contains:
- the exact redacted error and whether it happened before or after login;
- client version and approximate time, including timezone;
- the intended account/provider route and affected model;
- a request identifier, if the service supplied one;
- what changed immediately before the failure.
Exclude API keys, login codes, private session links, and full configuration dumps. If no relevant setting changed, repeated reinstallations and retries add little diagnostic value.
When an Agent.Space route is relevant
If you are evaluating a different model-access route for your existing CLI, inspect the Agent.Space Model API for current compatibility, configuration, models, and costs. That is a separate integration choice—not a promise to repair or restore an Anthropic account.
If you instead want to work through Agent.Space's browser interface, open a Workspace, choose an available Agent/model combination, and begin with a small authorized task. Confirm that the environment and billing match your intention.
A remote Mac is useful when the missing piece is a computer or desktop environment. It is not the default remedy for a permission error.
