Unable to access Code Server after server restart

After my instance is stopped due to out of credits, I topped up and restarted the instance successfully. However, when trying to access the NemoClaw chat ui or even code server, I encountered this error (below). I suspect after restarting Cloudflare doesn’t get updated or maybe mapped to the new IP after server restart?

Error 1043

Cannot find Access application

What happened?

You requested a page on a website (code-server0-xxxxxxxxxxxxxx.com) protected by Cloudflare Access, but something went wrong while loading its configuration.
