520 Origin Error

Recommended Posts

From my C# WinForm app, I am getting "(520) Origin Error" a lot this morning. Is server overloaded or has something changed? I get the error when I call to AUTHENTICATE. 2 out of 10 it would go through fine without error. After Authenticating I VALIDATE the session, and I get the same error again. 

HttpWebResponse Error in https://ciapi.cityindex.com/TradingAPI/session/ : The remote server returned an error: (520) Origin Error.

 

I also tried from Postman, randomly I get the same error, may be 1 in 10. Any idea?

Hello Superee,

There was a service interruption yesterday/overnight due to frontdoor issues with Azure affecting access. This should be resolved now so when you next use the API there should be no further problems.

Apologies for any inconvenience caused.

Kind Regards, PM
