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.
