Register ends with 502 error

suparomana

Hello everyone,

I have a problem with the registration. No registration could be completed. Everything is fine (inline validation etc.) till the submit-button is pressed. After that, the page reloads and the following error message is shown:

Registrierungsfehler
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>502 Proxy Error</title> </head><body> <h1>Proxy Error</h1> <p>The proxy server received an invalid
 response from an upstream server.<br />
 The proxy server could not handle the request <em><a href="/register">POST&nbsp;/register</a></em>.<p> Reason: <strong>Error reading from remote server</strong></p></p> <hr> <address>Apache/2.2.15 (CentOS) Server at my.domain.de Port 80</address> </body></html>

and this error is in the browser console:

and on the serverside i have these errors:

I'm pretty sure, that the registration was working before I upgraded to 1.6.0 Did you changed there anything in this process?

Everything else is working fine. Creating posts, chat, upload files, upload and change profile images etc.

On the serverside I have to use not the perfect configuration with apache 2.2 (without mod_wstunnel), but it worked pretty well.

Thanks for any help,
Chris

What version did you upgrade from?

Thats the log for your reverse proxy, can you check the nodebb log for errors?

@pitaj here is the nodebb-log. Actually nodebb crashes after submitting the register form.

nodebb-plugin-registration-notification must not be compatible with your version of NodeBB.

<baris>

Try updating the plugin to 1.2.1, that might fix the crash.

Thank you @PitaJ and @baris ! It was the plugin. I had installed the 1.2.1, but it does not worked. I uninstalled the plugin and registration i working fine again.
