using v1.0.3  
on rpi 4b newest rassbian lite  
over internet (https + password)  
i have got set my domain on duckdns org  
everything works like a charm when i am connecting to my node-red through  
[https://example.duckdns.org:1880](https://example.duckdns.org:1880)  
then i created virtual host in apache to maintain my node-red through subdomain like  
[https://node-red.example.duckdns.org](https://node-red.example.duckdns.org)  
and it looks like everything works like a charm but **i dont get any debug data!**  
a have tried everything  
here's my config file in apache

I haven't used Apache in a long time but I think you might be missing the websockets proxy?

I am getting lost connetion with RewriteEngine sollution. With proxy\_wstunnel (which i used)

```auto
ProxyPass /comms wss://example.duckdns.org:1880/comms
ProxyPassReverse /comms wss://example.duckdns.org:1880/comms

```

OK, I may be steering you wrong anyway. I just had a quick look and I realise that I don't think the debug data takes the path that I thought it did. I'd need to look at the connection to my Pi to see what is happening. Unfortunately, I need to do some paid work just now ☹ I'll try to look at it later unless someone else has been able to help by then.

I'm assuming that you are running the NR Editor across the Internet with the NR server running on your local network?

If that is the case, unless you are outputting debug to the NR log as well as the sidebar, I don't think it leaves the browser? So it is possible that it isn't a network issue and you should certainly check the browser's dev console to see if there are errors there.

Yeah i am running NR on my local network. I set debug node to output info to system console as well to debug window and i am getting timestamp on node-red-log but nothing on browser debug window... This is really confusing. After sometime it works and debug data is in debug window but its not predictible

I discovered something. When i was on my node-red site and i restarted my apache2.  
Client calls for wss://node-red.example.duckdns.org/comms  
After that everything works fine. Why i must wait for it in normal environment.

and when i first connect to node-red i got this (pending state):

I gave up on apache2 and switched to nginx and everything works flawlessly!  
here's my script

```auto
server {
        listen 443 ssl;
        server_name node-red.example.duckdns.org www.node-red.example.duckdns.org;
        ssl_certificate /etc/letsencrypt/live/example.duckdns.org/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/example.duckdns.org/privkey.pem;

        location / {
                proxy_pass https://example.duckdns.org:1880;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
        }
}

```
