Answer 1

Someone on your network appears to be censoring 4 out of the 5 the default obfs3 Brides that are distributed with Tor Browser. You will need to obtain a different set of Bridges from BridgeDB, and configure Tor Browser to use them (Step 2 and Step 3 from the link, with the corresponding documentation).

Answer 2

To resolve this issue, Open Tor browser => Click on Configure button => select Tor is censored in my country option => Click on Request a new Bridge => enter captcha then click Submit.

you will get a Bridge as shown in below image.

Still, you face connection failure issue try Requesting a new Bridge as mentioned above.

Answer 3

It looks like your ISP might be blocking Tor, using DPI (Deep Packet Inspection). Try using Pluggable Transports. You can download it here: https://www.torproject.org/docs/pluggable-transports.html.en#download

Here is a great tutorial on how to set it up: https://fteproxy.org/help-client-with-tor

Note: You need to download Pluggable Transports, only if you, for some reasons, are using older versions of TOR. In the latest bundles its already inside.

Answer 4

In addition to what Yawning Angel already wrote: You should select a pluggable transport like obfs4 from BridgeDB. This method is quite censor-ship resistant and often not blocked.

Besides from visiting the website you can also write a mail to [email protected] from a RiseUp, GMail or Yahoo! address with the subject get transport obfs4. The BridgeDB will send you some bridge addresses.

Within the Tor browser you click on the green onion and select the Tor network settings. When you check "My ISP blocks connections …" a submenu will open and you can paste the bridge lines there. Tor Browser will try to use the pluggable transport and you are able to use the net again.
