Stuck at 10%: Finishing handshake with directory server. 19:09:32 PM.110 Bootstrapped 10%: Finishing handshake with directory server 19:09:31 PM.623 Bootstrapped 5%: Connecting to directory server My friend who uses Tor Browser and uses the same connection as me can connect to the network and use Tor Browser. I check the log and it says problem bootstrapping, stuck at 10%. When I try to connect, it failed to establish connection with the network after waiting for a long time. The most commonly used bridges are obfs4.I've just started using the latest Tor Browser, connecting through my university connection. Snowflake sends your traffic through WebRTC, a peer-to-peer protocol with built-in NAT punching. meek_lite makes it look like you are using a Microsoft web site. Meek transports make it look like you are browsing a major web site instead of using Tor. Obfs4 bridges makes Tor traffic look random, and also prevents censors from finding bridges by Internet scanning. Obfs3 and scrablesuit bridges are deprecated. Vanilla bridges do not use pluggable transport at all, but like other bridges, they use servers that are not listed publicly. They use different methods of circumventing censorship. Several types of pluggable transports can be used with bridges: obfs4, obfs3, scramblesuit, meek_lite, and snowflake. Pluggable transport is designed to transform ordinary Tor traffic to a special one, which is impossible or very difficult to block. But you can bypass blockage by using bridges with pluggable transport. Also, in some countries, ordinary Tor entry servers are blocked, and/or Tor network is blocked by DPI. Using bridges in combination with pluggable transports helps to disguise the fact that you are using Tor, but may slow down the connection compared to using ordinary Tor servers.

Like ordinary Tor servers, bridges are run by volunteers unlike ordinary servers, however, they are not listed publicly, so an adversary cannot identify them easily. Tor Bridge is the first server in the common chain of Tor servers, which is required to protect your privacy. Ordinary Tor connection Tor with Bridge connection
