Error 403: Setting Public Artifact url

[alwaysharsha]

I am trying to setup the Slack Integration with TeamCity 2018.2.3

It's failing with the below error
403 Forbidden: Responding with 403 status code due to failed CSRF check: request's "Origin" header value "http://ftltctest.eng.company.net" does not match Host/X-Forwarded-Host header values or server's CORS-trusted hosts, consider adding "Origin: https://teamcitytest.eng.company.net" header.

Please provide me guidelines on this.

@alwaysharsha could you provide more information, when it happens and what are your actions to become this message?

When i enable the Slack plugin and fill the OAuth, Name and Sender Url and hit submit. I am seeing the above mentioned error instantly.

is your TeamCity behind the proxy?

[alwaysharsha]

Yes, its behind NGINX proxy.

Please check your setting Administration -> Global Settings -> Server URL

The url matches the Server URL, attaching the screenshot

No, it’s not. https is not the same as http

I also noticed the same problem. It's not persistence.
