HI Team

I am using OpenRouteService on Self hosted. It was working fine for me. Now I want to implement alternative route bit when I implement alternative route its throw error like :  
Request parameters exceed the server configuration limits. With these options, the approximated route distance must not be greater than 100000.0 meters.  
Without alternative route its return direction more then 100000 distance but when I use alternative route its throw error.  
How to increase limit with alternative route  
This is my config file:

Hi @RajeshVE22,

normally `maximum_distance_alternative_routes` should be the parameter to increase. But that should already be set to `1000000`. Not sure if you copy pasted the error message and the error output doesn’t match the config, or if it’s a typo and missing a 0 in the error.

You could try again with increased value. But computation time will also increase.

Best regards

Not working  
Throw this error:

API Error: {  
error: {  
code: 2004,  
message: ‘Request parameters exceed the server configuration limits. With these options, the approximated route distance must not be greater than 100000.0 meters.’  
},

Hi  
Any one know how to increase distance with alternative\_routes
