Can't connect to SMB shared Storage from Ubuntu 18.04

i have an external hard drive connect to my TP-Link router and shared using USB Share, i am unable to connect to this Share from Ubuntu, i can only see shared volumes but can't gain access. I can connect to it from Windows and even from my Android device using X-plore File Manager. What can i do ? My router is old and it supports only SMBv1 shares.
