I created a couple of custom components and configured authentication for them. The URL is redirected to the Pega login page and, after logging in, I land on the Authentication Successful page as expected.
This issue appears to be caused by network restrictions. Could you please check whether the IP address of your Labs instance (or the environment from which you are accessing the application) can be whitelisted? If whitelisting is not already in place, I would recommend reaching out to the Network team to allow the required IP addresses. This may help resolve the connectivity and fetch-related errors you are encountering.
Thank you for the response, The IP for my system has been whitelisted in the system and I have saved the Authentication profile available in the environment that authenticates the DX component builder package. However, I still face the same error. Are there any other configuration steps I am missing
