I am using the latest version of Tor, and I can't seem to connect to the obfs4 bridge that comes with the bundle anymore. Only obfs3 works but it is too slow! I tried grabbing alternate bridges from bridges.torproject.org and none of them would work. Reinstalling the program did not fix the problem, and neither did running as administrator. Please help, I live in the United States. The wifi hotspot I use blocks tor connections so I have to use bridges. Obfs4 used to work last month and now it doesn't. I am using Windows 10.enter image description here

  • Trying a meek transport may be worth a try. Mar 24 '17 at 18:56
  • @P. Gerber thanks for reaching me, but the meek transports don't work. Mar 25 '17 at 14:16
  • It makes no sense that obfs4 doesn't work but obfs3 does, unless they're actively recognising obfs3 and allowing it. Could the censorship be based on both a blacklist and ports?

  • Same here. Used to work, but 7.0.a2 won’t connect via the default obfs4 bridges. I too am connecting through a portal and it always worked here. It will connect after I uncheck the "does your ISP block or censor connections" box. Once it connects I can check the "my ISP blocks connections" box and it works fine. It’s only an issue when starting. I have a bunch of additional obfs4 bridges, but every time I use them it connects to the same UK server first. Might change if I rearrange their order since I don’t believe Tor currently randomizes them. As I added new ones I put them in numerical orde Mar 26 '17 at 16:38
  • Also could they have added some captive portal mechanism that you need to go through first?

Try using other pluggable transports such as:

  1. meek-amazon
  2. meek-azure
  3. fte
  4. ...

If no one works then try to use IPv6 normal bridges (which you can get at bridges.torproject.org).

  • None of the transports work except for obfs3, which is as slow as dialup Internet. I checked the website and they don't have any IPv6 addresses on there. Obfs3 bridges from the site don't work for me either. I added a picture of the log file to see for yourself. Mar 25 '17 at 14:42

I just had to download the new update that came out recently today and it fixed the problem for me. I am able to use obfs4 now. I appreciate those who tried to help!
