Microsoft365 GraphAPI returning "Connection reset"

ohsoko-hiroshi 6

We are performing HTTP requests for file downloads from a Java program (version:7).

There was no problem before, but since the other day, the HTTP request periodically results in "java.net.SocketException: Connection reset" for several hours, and the file download fails.

I can't find any maintenance information for GraphAPI, but have there been any changes?

The same event is occurring on all IP addresses that were able to resolve the name (graph.microsoft.com) during communication.

Share the detailed info about the API call that you're trying and the error that you got.

I use the "Download the contents" link below.
The HTTP Request is in the format "GET /me/drive/root:/{item-path}:/content".

driveitem-get-content

Here is the error I got.
If you need any other information, please let me know.

org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://graph.microsoft.com/v1.0/me/drive/root:/dir_name/dir_name/file_name:/content":Connection reset; nested exception is java.net.SocketException: Connection reset

We are using trying to achieve the same through PHP and it is a simple HTTP call, it randomly gives the connection reset by peer

Yes, it works intermittently. Connection reset by peer is a frequent message when the call is made from a Linux server

are you using any kind of certs? Because we cannot get the certs from microsoft, I am using dummykeystore, to create ssl socketFactory as below with TLSv1.2 as below:

TrustManager[] dummyTrustManager = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}

public void checkServerTrusted(X509Certificate[] certs, String authType) { } } };

SSLContext sc = SSLContext.getInstance("TLSv1.2");
sc.init(null,dummyTrustManager,new java.security.SecureRandom());
HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
urlConnection.setSSLSocketFactory(sc.getSocketFactory());
urlConnection.setRequestMethod("GET");
urlConnection.setRequestProperty("Authorization", "Bearer " + token);

No, I am not. Don't know much about this space. I did check with Hostgator our provider and he said certificates enabled and the instance uses TLS 1.3

Nothing on the code though, its simple HTTP Get with OAuth token
