From those AirVPN forum links, it seems like an intermittent problem with the DNS test. So maybe it was just working when you tested the Windscribe servers. Just now, I tested an IVPN exit, and got a bunch of DNS servers associated with the exit host. If you always get results for Windscribe servers, even when others are failing, maybe there's something different about them. Just what that might be, I don't know.
Yes, Windscribe servers test is always successful and Ivacy always gets error for some servers. Anyway, it does seem nothing important. And other websites test successfully. Thank you for the info, guys.
I installed IvacyVPN 2 days back. I noticed the bandwidth usage was very high these 2 days. I didn't download anything with Ivacy, just normal browsing, these 2 days. I checked the bandwidth usage with NetLimiter. Ivacy used app 700MB. My primary VPN is ExpressVPN. I used it more than Ivacy these 2 days. NetLimiter shows used app 30MB. I now connected ExpressVPN, didn't browse, just checked with Task Manager. Network field for ExpressVPN remains at 0. I then connected IvacyVPN, didn't browse, just checked with Task Manager. Network field fluctuates 0.1MB, 0.5MB, 1.2MB, 1.5MB & went upto 3.0MB in 15 secs. I checked the bandwidth usage in these 15 secs for Ivacy. NetLimiter shows app 12MB. Any info?
