Doesn't work with brave-browser

[Hard687]

I used it in a debian vm and got error but with firefox it works. Both brave-browser and chromium have same error.

try proxydns_daemon method. search the issues here (closed and opened) for "browser" to find lots of tips and explanations.

I can't find explanation on starting proxychains4-daemon. sudo systemctl status proxychains4-daemon
Unit proxychains4-daemon.service could not be found. And in the config it is proxy_dns_daemon 127.0.0.1:1053 but what is 127.0.0.1:1053 and do I need to change it

I can't find explanation on starting proxychains4-daemon.

just run it in a different terminal. not everything requires a systemd service.

what is 127.0.0.1:1053 and do I need to change it

it's where px4-daemon is listening. it's the default value so you dont need to change it.

Tried proxychains4-daemon in another terminal but it wasn't showing output is it working? Even with proxydns-daemon I have same error.

it wasn't showing output is it working

it shows no output until proxychains4 uses it, with the appropriate configuration

[Hard687]

I still get same error with proxydns-daemon I can't start brave-browser

well, if you followed my advice and looked for other issues, then you will have noticed that these behemoths are difficult to hook. maybe there's some command-line flag to make it not use a sandbox. of course, you could also attach a debugger and figure out why exactly it fails and then tell me so it can eventually be fixed.

I have a similar error in chromium but only when proxy_dns is set. The issue does not occur when proxy_dns_old is used instead. This appears to be consistent with the comments currently in proxychains-ng/src/proxychains.conf that for "complex software like webbrowsers [the former] might not work and/or cause crashes." More specifically, it seems for me and the reporter above to complain about zygote_host_impl_linux.cc

The above report:

[4927:4927:1222/142650.125687:FATAL:zygote_host_impl_linux.cc(221)] Check failed: . : No such file or directory (2)

In my case the error was:

[446321:446321:0109/225707.426805:FATAL:content/browser/zygote_host/zygote_host_impl_linux.cc:221] Check failed: . : No such file or directory (2)

Hope this helps anyone
