REST connectors : The provided host name is not valid

Hi everyone,

I tried to create a REST connector (Project > connectors > REST) in with a Wm on-premise API endpoint, but I get the error :

The provided host name is not valid. Provide a valid host name and then proceed.

I verified the url by a postman request and also by a navigator request and it works but not in
Does anyone have an idea?


Hello Tahiri,

Is it possible to share the endpoint ?


Hello @Bharath_Meka1,

It’s a company’s private API so I can’t share it, but I can give some spécifications :
This API is generated from an OpenApi specification in Wm on-premise.
