Troubleshooting

Codex sent me to 127.0.0.1

This is expected. Codex uses a temporary callback on your own computer to finish browser sign-in. Your browser may show “Unable to connect” after Codex has already accepted the authorization and closed that callback.

1. Return to Codex and look for a successful login or connected status.
2. If Codex shows success, close the browser tab, restart Codex, and open a new conversation.
3. Retry authentication only if Codex reports that sign-in failed or still asks you to authenticate.

Sign-in keeps repeating

1. Remove or disconnect Mittalmar in your client’s connector settings.
2. Close and reopen the client.
3. Add Mittalmar again and sign in with the account you want to use.
4. Start a new conversation after connecting.

I cannot add Mittalmar in ChatGPT

Direct MCP setup in ChatGPT requires Developer mode. OpenAI says its availability can depend on your account and workspace policy, and using Codex inside the ChatGPT app does not confirm access to this separate control. If ChatGPT does not show a Developer mode control, or the plus button opens Plugin Creator instead of an MCP connection form, your account does not currently expose direct setup. Plugin Creator packages integrations; it is not the form for pasting the Mittalmar server URL. See Connect with ChatGPT, or use Codex or Claude.

My client cannot find Mittalmar tools

• Confirm the connector is enabled for the current conversation.
• Make sure you signed in to the intended Mittalmar account.
• Confirm that account has an eligible subscription.
• Reconnect the server, restart the client, and open a new conversation.

Nothing was saved or generated

Creating projects, saving titles, and starting thumbnail generation require your confirmation. Ask the client to show the proposed action, then approve it when you are ready.

An AI action is unavailable

Ask Mittalmar to check your remaining AI budget. For a larger packaging workflow, ask for a cost estimate before running it.

My thumbnail is still processing

Generation runs in the background. Ask your client to check the generation batch it received:

I see links instead of images

Completed generations return image and thumbnail links. Whether they appear inline depends on your client, so clickable links are a normal result.

Claude says an owner must configure the connector

For some Team or Enterprise workspaces, an organization owner adds the custom connector first. After that, each member connects their own Mittalmar account.
