Dropbox .Net API UploadSessionStartAsync throwing httpclient timeout exception all of the sudden

rororo12

Hello, 

 

Our app all of the sudden is getting the following exception when trying to call UploadSessionStartAsync like so:
var result = await DropboxClientInstance.Files.UploadSessionStartAsync(body: memStream, uploadSessionStartArg:new UploadSessionStartArg());

 

Here is the exception:

The request was canceled due to the configured HttpClient.Timeout of 300 seconds elapsing.

 

The timeout was originally 100ms and I thought maybe there's some network lag so I increased the httpclient timeout to 5 mins (or 300 seconds) when initializing the Dropbox Client like so like so:

 

var dbxConfig = new DropboxClientConfig();
dbxConfig.HttpClient = new HttpClient();
dbxConfig.HttpClient.Timeout = new TimeSpan(0, 5, 0); //setting httpclient timeout to 5 mins or 300 seconds

var tokenResult = await DropboxOAuth2Helper.ProcessCodeFlowAsync(code: input, appKey: dbxAppKey, appSecret: dbxAppSecretKey, redirectUri: null);

 

DropboxClientInstance = new DropboxClient(appKey: dbxAppKey,
appSecret: dbxAppSecretKey,
oauth2AccessToken: tokenResult.AccessToken,
oauth2RefreshToken: tokenResult.RefreshToken,
oauth2AccessTokenExpiresAt: tokenResult.ExpiresAt.Value, config: dbxConfig);

 

I'm using V7 of the .net library 

 

Anyone know why all of the sudden I would be getting an httpclient timeout when it was working fine for months without an issue?

 

Thanks in advance for the help!

@rororo12 Like Здравко recommended, I suggest troubleshooting your environment to see if there's anything wrong with your network connection that would be interfering with the network requests to the Dropbox API servers. (For example, is there any proxy, firewall, etc. that may be causing an issue?) I'm not aware of an issue that should be preventing these calls from completing. I just tried out your code using v7.0.0 of the Dropbox .NET SDK and it ran successfully for me.
