Getting error - app.powerbi.com refused to connect after embedding the report in web portal

Hello Experts,

I got into the error - app.powerbi.com refused to connect for the embedded report of web portal

Initially everything was perfect and fine after embedding the report into a web portal. 

But few days ago this issue started

The link looks something like this

https://app.powerbi.com/reportEmbed?reportId=fdc8576e93b-4865-ab57-4a918fadf991c&autoAuth=true&ctid=...

followed by the filter 

&$filter=activation_actuals_forecast/ ResellerID eq '[PartnerProId]'

So the together the link is 

https://app.powerbi.com/reportEmbed?reportId=fdc8576e93b-4865-ab57-4a918fadf991c&autoAuth=true&ctid=...

The report has four datasets and all are connected with proper relations. All are imported connections

When I use the link withour any parameters(filter) it works but the requirement is to pass the parameters(filters) so that as and when the parameter value changes in the web portal the report will filter for that value.

Not sure what is wrong with the report. Nothing has changed but all of the sudden embedded report stopeed working and the page looks like below

Seeking experts help here to address the issue.

Thanks in advance!

Regards

Sandesh
