Is tpbproxy still the best way to access TPB safely? or How reliable is tpbproxy for unblocking TPB t

Not just you—tpbproxy has been flaky. Try switching to a different proxy URL like tpbproxy.uk or tpbproxy.xyz. Sometimes the old ones get overloaded.

But mirrors are better imo. tpb20.uk is my current favorite.
