Error registering New Account, Connection has been lost

[H7]

Connection to NodeBB has been lost error when registering an account / login to NodeBB.

• community.h7.org/register won't allow registering new accounts. websocketstest.com gives no errors, all seems good
• ./nodebb dev output has NodeBB address in use errors:

You can't run ./nodebb dev while an existing nodebb process it running. EADDRINUSE means the port is in use, usually by another NodeBB process.

[H7]

I understand, so what could be the problem, causeing the "Connection to NodeBB has been lost error"?

[PitaJ]

Make sure url in config.json is set to exactly the URL at which you access your forum.

[H7]

Yes, all seems ok in config.json. In the meantime I did a new install with latest OS(Debian 9)/Node.js/etc., was able to log-in however, the registration still unresponsive and all admin functions are available but no changes can be saved while the same "Connection to NodeBB has been lost error" is present.

[H7]

Found something in console that may help:

Failed to load resource: the server responded with a status of 403 (Forbidden)  http://community.h7.org/socket.io/?EIO=3&transport=polling&t=Lxq7d38

[PitaJ]

@h7 are there any errors in the browser console?

[H7]

@pitaj yes, 40+:

[PitaJ]

@h7 Can you provide your nginx config and nodebb config.json?

[H7]

Wrong nginx config. I need the site config with the reverse proxy settings etc.

Does ./nodebb stop then ./nodebb dev stop those errors?

[H7]

@PitaJ
./nodebb stop gives response: NodeBB is already stopped.

./nodebb dev gives the errors:

How did you start NodeBB?

[H7]

@pitaj started with ./nodebb start now just checked with ./nodebb restart and while community.h7.org is accessible, I get the message NodeBB could not be restarted, as a running instance could not be found.

./nodebb log results are:

7/10 03:48:59 [21010] - error:  Error: listen EADDRINUSE 0.0.0.0:4567

pkill -9 node then ./nodebb restart and service nginx restart fixed all problems. It seems a previous NodeBB was still running in memory

@PitaJ thans a lot for the help! Truly amazing app with excellent community support!
