Limitations
This page lists all current restrictions for our products.
Blocking of specific websites
The following are unavailable through proxies:
Banking websites (online banking, bank personal accounts)
Government portals and websites, as well as websites in the
.govand.edudomainsPayment processors: Stripe, PayPal (including Yahoo)
This is a regulatory requirement aimed at limiting fraudulent activity. This restriction does not apply to crypto services and payment systems such as exchanges.
Applies to all products except Mobile proxy.
Stripe and PayPal are available on Datacenter and ISP proxies.
Additional restrictions on Residential proxies:
Microsoft and Apple services are unavailable on Standard Residential / Unlimited Residential / Premium Residential.
UDP on Residential proxies
UDP does not work on Standard Residential and Unlimited Residential in the US location 🇺🇸
This is not our restriction. In early 2026, US providers prohibited incoming UDP connections without prior initiation from inside the network. Because of this, UDP Associate on proxies stopped working in this region.
Standard and Unlimited support UDP in other locations, subject to the general port restrictions.
Premium Residential supports UDP in all locations except certain cities and devices running macOS or iOS.
UDP port restriction for Standard and Unlimited
Standard and Unlimited currently allow UDP traffic only to destination ports 8443, 8080, 3478, and 19302. Other UDP port ranges are blocked. UDP remains completely unavailable in the US location.
Premium Residential is not affected by this port restriction. Only the existing exceptions for certain cities and macOS/iOS devices apply.
static_mode2 and macOS/iOS devices
static_mode2 corresponds to Static in the Session mode field for Premium Residential. In this mode, the proxy keeps the selected device and does not switch the session to another device if the current one temporarily goes offline.
If the selected device is unavailable, the generated proxy may stop responding until the device returns or the TTL expires. To get another device immediately, generate a new proxy with Generate proxy.
Filtering by Device OS: macOS or iOS significantly reduces the available pool. Combining the OS filter with a city and provider may leave no matching devices, especially in Tier 2 and Tier 3 countries. UDP is also unavailable on some macOS/iOS devices and in certain cities.
