Hi there,
I’m encountering an issue with the Builder.io preview in my Next.js 15 App Router project. The preview isn’t loading when I use my credentials.
Interestingly, it works fine for other team members in our organization, even though we’re all using the same role—Admin. I’ve verified this by testing with different accounts.
Could you please help me troubleshoot this?
Hi!
My name is Veronika and I am a Customer Engineer here at Builder.
Could you verify that your server is running ?
Here is another piece of documentation that may be helpful as well.
Thanks!
Hi Veronika,
Yes, our server is running during testing, and I’ve carefully followed the documentation you shared. However, we’re still encountering the same issue.
We did a deeper investigation and discovered that some of our coworkers in other regions, who have the exact same role assigned, are able to access the preview without any issues. This suggests the problem is isolated to my account.
To further test this, I created a new account and accepted an invitation with the same role but surprisingly, both accounts are facing the same issue.
We also confirmed that both my coworker and I are working from the same commit origin, which means the codebase is identical. This further indicates that the issue is specifically tied to my account setup rather than the code itself.
Would appreciate any further insights you might have. Thanks in advance!
Can you verify your local dev server is running on the correct port?
If there was another process already using port 3000 when your started your dev server, then the tooling may have chosen another port number to run on.
