I wanted to test the meek pluggable transport. It can't connect. The standard Tor browser works on this PC (Windows 8.1, 64-bit) without problems but not the meek version. Below is the log:

Thanks so much for taking the time to test and write this report. What you describe sounds like this ticket:
"tbb bundle with meek takes (literally) hours to connect" https://trac.torproject.org/projects/tor/ticket/11612
I wasn't able to reproduce the problem, and the reporter hasn't replied back yet.
What version were you using? Was it version 3.6.2-meek-1, or another version?
The first thing we should try is to enable logging in meek-client. Edit the file Data\Tor\torrc-defaults. This line is at the bottom:
ClientTransportPlugin meek exec ./Tor/PluggableTransports/terminateprocess-buffer ./Tor/PluggableTransports/meek-client-torbrowser --exit-on-stdin-eof -- ./Tor/PluggableTransports/meek-client --url=https://meek-reflect.appspot.com/ --front=www.google.com
Add "--log meek-client.txt" to the end of the line, so it looks like this:
ClientTransportPlugin meek exec ./Tor/PluggableTransports/terminateprocess-buffer ./Tor/PluggableTransports/meek-client-torbrowser --exit-on-stdin-eof -- ./Tor/PluggableTransports/meek-client --url=https://meek-reflect.appspot.com/ --front=www.google.com --log meek-client.txt
Then try running the browser again. It will create a file called meek-client.txt. Send that file to me. You can of course check what's inside it. What we're looking for is lots of "error in handling request: EOF" like in https://trac.torproject.org/projects/tor/ticket/11612#comment:2.
Then, if you feel up to it, please try following the steps in https://trac.torproject.org/projects/tor/ticket/11612#comment:1 to increase the internal timeouts.
