[JiwaniZakir]

The issue is in bolna/local_setup/README.md, where the agent examples links point to https://examples.bolna.dev/ but that domain/subdomain is not yet live or has not been configured. This is likely because the examples.bolna.dev subdomain either hasn't been set up in DNS, the hosting for that subdomain isn't deployed yet, or the links were added to the README prematurely before the examples site was ready. Until the subdomain is active, the links will remain broken for anyone following the local setup guide.
