Unable to Connect to SQL DB

[AndFig]

Recently out of nowwhere im getting this error message

And this other one on another report when trying to apply changes made on power query

 It was working this morning and i don't know what could be happening.

The tables are not that big, and even so I have several SQL queries filtering data I don't need. 

To make things worse the conneccion from SQL SMS works without any issue and I can get data from it

I would appreciate any help

@AndFig , Go to datasource setting and clear permissions and try again
