In your opinion why is not it more accessible?
You asked four times. We can't see your systems or your exits so we don't know. Run your own restricted exits on your own various computers, starting with those you can reach it with via clearnet, then route all your traffic out those exits and do more testing, beginning with tcpdump or some form of log/traffic analysis on both the exit and webserver. There's obviously blocking or misconfiguration involved. Let us know what you find.
