401 Error on rest apis for my fresh website

Dear,
Their is a strange 401 error comes in basic rest APIs.
For example: https://parosi.techchef.org/wp-json/wc/v3/products/categories?consumer_key=ck_f76c28eae983eb9b237d6bb81dd5b6c1ee35d16f

I have already checked and trouble shoot following steps.
1- Enable the legacy REST API is checked
2- I have made new rest api and applied the same consumer key
3- I created new admin and tried
4- I replace htaccess with default wordpress
5- I have upgrade both wordpress and woocommerce version to latest
6- I have disabled all other plugins

But none of the things work still, rest every thing is working fine but rest-API authentication for woocommerce does not
