My goal: Establish Tor network from Tor Browser (in Windows 10) using a user-provided Tor Bridge.
What I did so far: Following this Tor Wiki, I set an obfs4 Tor Bridge up in an Ubuntu 16.04 machine. I found that the setup is successful. I checked from syslog and Tor Metric. The syslog showed:
Tor: Bootstrapped 0%: Starting
Tor: Starting with guard context "default"
Tor: Bootstrapped 80%: Connecting to the Tor network
Tor: Signaled readiness to systemd
systemd: Started Anonymizing overlay network for TCP.
Tor: Registered server transport 'obfs4' at '[::]:44815'
Tor: Opening Socks listener on /var/run/tor/socks
Tor: Opening Control listener on /var/run/tor/control
Tor: Bootstrapped 85%: Finishing handshake with first hop
Tor: Bootstrapped 90%: Establishing a Tor circuit
Tor: Tor has successfully opened a circuit. Looks like client functionality is working.
Tor: Bootstrapped 100%: Done
Tor: Now checking whether ORPort ..*.:9001 is reachable... (this may take up to 20 minutes -- look for log messages indicating success)
Tor: Self-testing indicates your ORPort is reachable from the outside. Excellent. Publishing server descriptor.
The Tor metric showed the Tor Bridge has Fast, Running, V2Dir, and Valid flags so far and the Advertised Bandwidth is 59 kiB/s.
Now from a laptop machine (Windows 10), I have installed Tor Browser 8.0.2 and tried to connect Tor network using the private obfs4 bridge. I failed to do that. I have tried some troubleshoots but nothing worked. When I used built-in Tor bridges from the configuration of the Tor Browser, the connection established. Even when I used bridges after requesting BridgeDB and passing a CAPTCHA, the connection formed successfully. But when I configured the Tor Browser giving credential of my own Bridge, it didn't work.
Can you please help how to solve this issue?
