I am trying to relay the WebSocket connection of V2Ray with Apache according to This post, and the snippet below worked before.

<LocationMatch "/{ws_path}}/">
    ProxyPass ws://127.0.0.1:{port}/{ws_path}/ upgrade=WebSocket
    ProxyAddHeaders Off
    ProxyPreserveHost On
    RequestHeader set Host %{HTTP_HOST}s
    RequestHeader set X-Forwarded-For %{REMOTE_ADDR}s
</LocationMatch>

However now I wanted to replicate it on a new machine, Apache2 cannot be started, and the error message says:

Jun 13 11:22:22 localhost apachectl[1519]: AH00526: Syntax error on line 32 of /etc/apache2/sites-enabled/whc2001cloud.tk.conf:
Jun 13 11:22:22 localhost apachectl[1519]: ProxyPass unknown Worker parameter
Jun 13 11:22:22 localhost apachectl[1519]: Action 'start' failed.
Jun 13 11:22:22 localhost apachectl[1519]: The Apache error log may have more information.
Jun 13 11:22:22 localhost systemd[1]: apache2.service: Control process exited, code=exited status=1
Jun 13 11:22:22 localhost systemd[1]: Failed to start The Apache HTTP Server.

If I take away the upgrade=WebSocket parameter, Apache2 starts, but V2Ray is unable to make connection correctly. I have already enabled mod_ssl, mod_proxy, mod_proxy_wstunnel and other related modules.

  • are you using apache 2.2 or apache 2.4? – c4f4t0r Jun 13 '19 at 12:34
  • @c4f4t0r It's Apache 2.4.25. – whc2001 Jun 13 '19 at 12:55
  • @Wwhc2001 I think that you are using the parameter option in the wrong way httpd.apache.org/docs/2.4/mod/mod_proxy_wstunnel.html, in any case, from doc, it sould work without this parameter by default – c4f4t0r Jun 13 '19 at 13:32

    @c4f4t0r Thanks, seems like it does work without that parameter. The connection failure is due to an invalid DNS record. – whc2001 Jun 13 '19 at 14:05

*Forgot to post the answer instead of commenting back then

Just remove the upgrade=WebSocket patameter and it should work without any problem.
