Describe the problem/error/question I am on the community edition of n8n. When I updated n8n and it broke my n8n api credential. I have restarted, deleted the credential, deleted and created a new api key, reinstalled n8n, but nothing has worked. I can confirm that other credentials still function. …

Hi @Jonathan_Sherman I just tested with 1.49.0 and it seems to be working fine. [CleanShot 2024-07-17 at 12.05.44@2x] [CleanShot 2024-07-17 at 12.06.09@2x]

Yes, I don’t believe it is something that affects everyone. However, I still have not solved it. It would be great if someone at n8n could help.

This is strange. Someone from n8n team will help you asap.

@Jonathan_Sherman Can you try using 127.0.0.1 instead of localhost?

Hey @Jonathan_Sherman , Can you share the full url you are using? The first issue was it couldn’t connect likely becuase it was usng ipv6 instead of ipv4 for localhost, The error now looks like the API key is incorrect.

Hi, thanks for that. Using http://127.0.0.1:5678 instead of localhost allows the credential to connect in my workflows. However, the API playground is still broken.

Perfect, I am not sure why the API playground would be broken though what error does that show?

That shows the 401 Error: Unauthorized
