Unable to properly athunticate my domain getting errors

Hello,

i tried to authenticate my domain eshopky.com with your plugin but whenever i try it says please add your domain to continue. only 1 time it shows me its activated and then i tried to import products for sample test and it was ok then when i tried to sync the products again it asks me add your valid domain to continue.

kindly help me what are these issues how i can start proper dropship business if i get these errors again and again.

regards,

Hasan Ahmed
