I'm using private proxies from yourprivateproxy.com. I travel for work and when I got set up in my hotel last night, I autodetected my new IP, updated my proxy list and uploaded them into Scrapebox. When I tested the proxies, I had 9 out of 10 return an "Error 407 proxy authentication required". I emailed yourprivateproxy.com for support this morning, but I haven't heard anything back yet. I was wondering if anyone else has ever had this error while using proxies with Scrapebox?
