I have opengrok container with port 8080 exposed on the podman network and mapped to 9000 on host network.

If I do this externally it works: curl http://hostname.domain:9000/api/v1/file/content?path=/path/to/file
But from another container using the internal port and hostname: curl http://opengrok:8080/api/v1/file/content?path=/path/to/file then I get:

<!doctype html><html lang="en"><head><title>HTTP Status 401 – Unauthorized</title>
<style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style>
</head><body><h1>HTTP Status 401 – Unauthorized</h1><hr class="line" /><p>
<b>Type</b> Status Report</p>
<p><b>Message</b> Unauthorized</p><p><b>Description</b>
 The request has not been applied to the target resource because it lacks valid authentication credentials for that resource.</p>
<hr class="line" /><h3>Apache Tomcat/10.1.43</h3></body></html>

I'm pretty stumped what could be the difference

to clarify this problem doesn't happen with search:

different container:

# curl http://opengrok:8080/api/v1/search?def=func
{"time":9,"resultCount":1,"startDocument":0,"endDocument":1,"results":{"/path/to/file.c":[{"line":"<b>func</b> (void)","lineNumber":"145","tag":"function"}],}}

# curl http://opengrok:8080/api/v1/file/content?path=/path/to/file.c
<!doctype html><html lang="en"><head><title>HTTP Status 401 – Unauthorized</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 401 – Unauthorized</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Message</b> Unauthorized</p><p><b>Description</b> The request has not been applied to the target resource because it lacks valid authentication credentials for that resource.</p><hr class="line" /><h3>Apache Tomcat/10.1.43</h3></body></html>

I think this happens because the request to the exposed port appears to come from localhost while the other request does not. The API docs say up front:

Besides /suggester, /search, /system/ping and /metrics endpoints, everything is accessible from localhost only unless authentication bearer tokens are configured in the web application and used via the 'Authorization' HTTP header (within HTTPS connection).

For the auth token configuration directives see https://github.com/oracle/opengrok/wiki/Webapp-configuration#configuration-tunables
