Yeah, also the api's are not working even with proper IP address.
Btw your IP address wrong. The max a number can be 255.
So 345 and 678 is not correct in yours.

@admin It works with trading API key. Trading api keys allows history and market data also now

@d321860 you can edit the secondary static IP from the dashboard.

@jayesh_sapkale The IP address from where the order API originates should be same as that of the IP added while making the API key. Or else, the above error will come.

@MAWJ104 Yes you can do that.

@sejpalsinh As mentioned earlier, create a new static IP from Networking page and attach the IP with your instance of droplet.

@prashant_extreme Outside of market hours, this is very common error.

@diwakarpant16 You can put any IP address in to order to use it for data only purpose.
