Troubleshooting

This page collects common issues encountered when hosting or accessing flyers.

Tor connectivity

Ensure Tor is allowed through your firewall. On systems using ufw you may need to run sudo ufw allow tor.
Some networks block Tor entirely. If you cannot reach onion services, try connecting over a different network or use a Tor bridge.

Placeholder binaries

The files in voxvera/resources/tor/* are not real executables. Install tor and obfs4proxy yourself (e.g. apt install tor obfs4proxy) then set TOR_SOCKS_PORT and TOR_CONTROL_PORT before running voxvera serve or the Electron GUI. OnionShare uses these values with its --use-running-tor argument. Running scripts/download_tor.sh can also populate the missing files automatically.

Firewall rules

If voxvera serve fails to start OnionShare, verify that outbound connections on ports 9001 and 80 are permitted.
Corporate or university firewalls can block the hidden service ports required by Tor.

SELinux

On SELinux-enabled distributions you may see permission denied errors when OnionShare writes to the host directory.
Run sudo chcon -Rt svirt_sandbox_file_t host or disable SELinux enforcement for the folder.

OnionShare crashes

If the GUI shows "OnionShare exited unexpectedly" check the log file host/<subdomain>/onionshare.log for details. This usually points to network connectivity problems or a missing dependency. Running voxvera serve from the command line can provide additional error output.

If problems persist, consult the OnionShare and Tor documentation for more advanced configuration tips.

Electron GUI

If npm start fails with spawn voxvera ENOENT, the voxvera command is not in your PATH. Install it with pipx install git+https://github.com/PR0M3TH3AN/VoxVera.git or run ./install.sh from the repository.

Missing dependencies

Run voxvera check to see which required tools are present. The command verifies node, javascript-obfuscator, html-minifier-terser, jq, qrencode, onionshare-cli, and other helpers, then prints a summary of any that are missing so you can install them.
