General troubleshooting

The first troubleshooting step in this situation is to curl your endpoint:

curl -I -v https://[your endpoint]:[port]/admin/healthcheck

The output should look something like this:

❯ curl -I -v http://[your endpoint]:[port]/admin/healthcheck
*   Trying [::1]:[port]...
* Connected to localhost (::1) port [port]
> HEAD /admin/healthcheck HTTP/1.1
> Host: [your endpoint]:[port]
> User-Agent: curl/8.4.0
> Accept: */*
>
< HTTP/1.1 200 OK
HTTP/1.1 200 OK
< Connection: keep-alive
Connection: keep-alive
< Content-Length: 0
Content-Length: 0
< Date: [date]
Date: [date]

<
* Connection #0 to host [your endpoint] left intact

If you do not get an output like this, send the following in a support ticket:

The output you do get from the above curl command
The output from the browser console
The .har file from the Network tab
1. Before collecting this, make sure you have the Network tab open, refresh the page, and cause the "Failed to Fetch" error to occur again.
2. For more detailed instructions on generating a .har file, see here.

A common source of error here is using self-signed certificates that your browser does not trust. The solution is to use a certificate from a certificate authority like Let's Encrypt and ensuring the entire certificate chain is in your truststore.

Kerberos

You may receive this error if you authenticate with Kerberos. To solve this, add https://cloud.stardog.com to cors.allowed.orgins in stardog.properties and restart your server. Read more here.
