I have integrated a Custom GPT with an external API using OAuth. The initial login works perfectly. However, after the OAuth access token expires, the GPT gets stuck on “talking to connector.” It does not immediately display the “Sign In” button or prompt for re-authentication.
The re-authentication flow only appears after I manually refresh the page or start a new chat.
I’m encountering the same issue with a custom GPT that uses an OpenAPI schema and JWT auth. After the token expires, there’s no re-authentication prompt — it just gets stuck on ‘talking to connector.’ Interestingly, I ran into this issue a while back too. Back then, I deleted the GPT and created a new one with the same custom actions — and it worked again for a few weeks. But eventually, the same issue returned. Now, I’ve created yet another GPT using the exact same OpenAPI schema, and this time the problem occurs right from the start. Something seems to be seriously broken in how token refresh or re-authentication is being handled.
