Hi,

I try to set up OAuth, according to https://www.hesk.com/knowledgebase/?article=110
My admin page has custom name 'mandel'.
My redirect url is:
https://hesk.mysite.hu/mandel/oauth_providers.php
I did set up that url in Azure, I checked it.
When I try to verify, I get this error:
"AADSTS50011: The redirect URI 'https://hesk.mysite.hu/helpdesk/mandel/ ... viders.php' specified in the request does not match the redirect URIs configured for the application '...'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal..."
Why I get 'https://hesk.mysite.hu/helpdesk/mandel/ ... viders.php' url in the error message?

1. Do you have any redirects set up from https://hesk.mysite.hu/mandel/oauth_providers.php to https://hesk.mysite.hu/helpdesk/mandel/ ... viders.php ?

2. what does the URL say in your browser bar when you are on the Hesk Oauth Providers page?

3. is your "Help desk URL" in Admin panel > Settings > General correct?

1. No, I don't.
2. https://hesk.mysite.hu/mandel/oauth_providers.php
3. https://hesk.mysite.hu/helpdesk -> I changed it to https://hesk.mysite.hu and the verification was successful.

Thanks for your help.
