We are having error code 401 when we're trying to set up connections between our sites and Shipstation.
This is our site:
We're running a B2C site on Magento 22.214.171.124 and followed all the installation steps provided in the tutorial. We also tried different API, upper/lower cases, all kinds of different ways and we believe there's nothing wrong in the web profile that they don't match to get the connection.
Please help us to solve the problem.
