Among the many proxy services, Astroproxy was the only one that could solve my problems with registration. Prices do not raise questions, quality does not, all proxies pass any checks. It might be worth copying the profile settings for some applications in the interface window, which is not immediately clear to the average user, in the format - username:password@ip:port. I purchased my proxy for the purpose of working with payment systems and am most pleased with the work of the support, which solves the problem to the very end, even if you have already forgotten about it.
