Hello,

today i have very interesting problem. Every app works last day without problems on .NET Framework, but today, when i trying to get access token, i get instantly error about Invalid user credentials. User on other laptop in company have same app and can login without problems, even when i tried my own creds, it works. On my laptop, when i try to get access token via oauth2 directly via browser, i can succesfully authenticate. but webbrowser on .net throw error as i mentioned on beginning and funny fact, sometimes after error i try to auth again and must proceed via captcha, and then i get authed...

Anyone who had this problem sometimes and know how to fix it? it works fine last day, but today is mystery day as i see.

Thank you.

Edit, it seems my account have captcha requirements. Even when i tried FTP via cmd, i get error 530 Box: CAPTCHA is required. Please log into www.box.com in a web browser, and then try again.I tried to login, but webbrowser dont ask for captcha and even when im logged in to box via browser, still getting this error.

Hi Bailando. We do not enforce any Captcha in our API. Are you on a corporate VPN or Proxy that might be throwing this CAPTCHA?

Bailando isnt using the API; they say they are using FTP via cmd.

I am also using FTP and it is saying to me "CAPTCHA is required" and i login via web browser and click the "I am not a robot" and login fine, but FTP continues to fail saying "CAPTCHA is required"; this is terrible!
