Gateway connection issue
Monika_85 Hi this is a known issue. Power BI team is working on it.

HI Monika_85 ,
The error message might be right - the gateway itself might not be running. I would first confirm that the gateway is up and running. Then, I would confirm that the Data Source is correct (which it probably is since you were able to select it), but worth checking on. Then, I would confirm that the userid you are using has access to that Data Source in the Gateway setting.
Since you mentioned that it failed in multiple attempts I would think it was permissions or the gateway not working as expected.
You might also want to make sure that the gateway is updated, it could be that your Power BI Desktop is significantly newer than the gateway (although when that happens the error message usually clearly states that the versions are different).
