Total Upkeep throwing an error when trying to make a backup

I bought this product and it does not work, it does not stop giving errors.
It does not load dashboard, it always gives an error.
I haven’t been able to make a backup for weeks. I am totally disappointed with the product.

I am sending you the log of the last error:
entering dashboard:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request

Reason: Error reading from remote server
