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 .gov and .edu domains

  • Payment processors: Stripe, PayPal (including Yahoo)

This is a regulatory requirement aimed at limiting fraudulent activity. The block does not apply to crypto services and payment systems such as exchanges.

Additional restrictions on Residential proxies:


UDP on Residential proxies (US)

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.

UDP works without issues in all other locations.
