I'm using private proxies from Buyproxies.org. They've always worked great for me in the past, both for browsing but also for different tools such as Scrapebox or GSA. But today when I got my proxies to use with Zennoposter I realized that they all work fine for the first page you load, but the second page you try to load just ends up loading for a minute or two before it completes. Same result with both the ZP browser and Firefox. I've had the proxies changed multiple times but no luck. They say that it looks fine on their end. Anyone got a clue what's causing it?
