v1.6.0 Suspected Nginx Problem
-
Upgraded from v.1.5.3 to v.1.6.0 as per the upgrade manual.
Browser fails to display pages when I follow a link. If the page is refreshed it loads but only displays the post text and not the markdown formatting.
No erros from ./nodebb log
Nginx error.log shows:
2017/10/01 00:04:52 [error] 537#537: *184 connect() failed (111: Connection refused) while connecting to upstream, client: 86.30.244.235, server: myforum.com, request: "GET /socket.io/?EIO=3&transport=polling&t=LxL2GT8 HTTP/1.1", upstream: "http://127.0.0.1:4567/socket.io/?EIO=3&transport=polling&t=LxL2GT8", host: "myforum.com", referrer: "https://myforum.com/"
My nginx configuration is from the docs with SSL.
If I bypass Nginx and access port 4567 directly in the browser, the forum displays correctly. This leads me to believe the problem is todo with Nginx.
Nodebb is running on Ubuntu 14.04, as per the installation instructions.
-
One possible reason may be, that your noddebb doesn't listen on localhost:4567, but on the local lan interface IP address only.
You can check that with 'netstat -nlp | more'

Have you read my post Tips to get 1.6.0 running after updating from 1.5.x ?
What you write is one of the problems I had. I solved adding two extra rules to nginx configuration. -
Browser fails to display pages when I follow a link.
Sounds like a Socket.IO misconfiguration.
My nginx configuration is from the docs with SSL.
I also had problems when I followed the docs. What I had to do was appending a definition the end of my
config.jsonfile:{ "url": "https://mydomain.tld", "secret": "uuid4 string", [...] "socket.io": { "origins": "http://mydomain.tld:* https://mydomain.tld:*" } }That one tells to accept connections coming from that domain.
If the problem persists, I also did some customizing my NGINX config:
/etc/nginx/sites-available/mydomain-tld-http.conf
# redirect everything to HTTPS server { listen 80; listen [::]:80; server_name mydomain.tld *.mydomain.tld; include /etc/nginx/snippets/acme.conf; return 301 https://mydomain.tld$request_uri; }# remove all subdomains from HTTPS server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name *.mydomain.tld; include /etc/nginx/snippets/tlsgzip.conf; return 301 https://mydomain.tld$request_uri; }# HTTPS forum server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name mydomain.tld; root /var/www/html; #just a fallback location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:4567; proxy_redirect off; # Socket.IO Support proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } include /etc/nginx/snippets/tlsgzip.conf; }As seen, there are some includes:
/etc/nginx/snippets/acme.conf
location ^~ /.well-known/acme-challenge/ { default_type "text/plain"; root /var/www/html; } location = /.well-known/acme-challenge/ { return 404; }This is just a snippet that makes EFF's CertBot configuration simpler.
/etc/nginx/snippets/tlsgzip.conf

About the SSL cyphers, that's a huge list I copied from an old tutorial and updated myself in order to keep an A+ grade at SSL Labs.
Nodebb is running on Ubuntu 14.04
I'm running it on a Ubuntu 16.04 VPS.

@sfner thanks for the detailed reply. I tried including socket.io definition to my config.json but it had no effect. I also tried adding all sub-domains to nginx conf but it too had no effect. For both efforts I checked the direct non-nginx and it worked.
Perhaps I should have added that it's running on a VPS that uses openVZ.

As a last random shot, the tutorial instructs you installing the 6.x version of NodeJS, but I ignored that and installed the 8.x one.
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs(I did the same thing for MongoDB (installing the latest version, ignoring the installing instructions), but as the database is working for you, I wouldn't touch it for now)

@unterm said in v1.6.0 Suspected Nginx Problem:

I simply skipped this. Sorry.
Try adding the NGINX's stable PPA and then upgrading the packages from your system:
https://launchpad.net/~nginx/+archive/ubuntu/stable -
Hi everyone,
I'm having the same issue... I reviewed and tried all the links here, also, if I bypass to port 4567 my forum works... I just ran out of options... do you have any updates? (I do not want to open another thread for the same issue)Cheers

@christian-mendieta You'll probably want to share your nginx config for NodeBB
-
@julian sure:

That would be:
{ "url": "https://mysite.tld", "secret": "97a8ebc8-dxx", "database": "mongo", "port": 4567, "mongo": { "host": "192.168.xx.xx", "port": "27097", "username": "nodebb", "password": "soeasy", "database": "nodebb" } } -
Any chance you can reset your config to just the bare-bones as defined in https://docs.nodebb.org/configuring/proxies/nginx/?
I'm looking at the
includes, which could literally be anything![😕](https://community.nodebb.org/assets/plugins/nodebb-plugin-emoji/emoji/android/1f615.png?v=4d49021a373 ":\")

OK, did some clean up, the problem persist, the nginx config now is:
server { listen 80; server_name mysite.tld; return 302 https://$server_name$request_uri; } #This is a redirect to allow only secure connections server { listen 443 ssl; listen [::]:443 ssl; ssl_certificate /etc/letsencrypt/live/mysite.tld/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/mysite.tld/privkey.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers 'AES128+EECDH:AES128+EDH'; ssl_dhparam /etc/ssl/certs/dhparam.pem; server_name mysite.tld; root /var/www/html/mysite.tld/public_html; index index.php index.html; access_log /var/log/nginx/mysite.tld.access.log; error_log /var/log/nginx/mysite.tld.error.log; # SSL block location ~ /.well-known { allow all; } # Deny access to .htaccess location ~ /\.ht { deny all; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:4567; proxy_redirect off; # New fixes.

Try removing
root /var/www/html/mysite.tld/public_html; index index.php index.html;Probably won't fix it but it's worth a try. Also, validate your nginx configs and try restarting nginx completely (as opposed to reloading)
-
Thanks for your answer, and you're right it didn't fix the problem even with nginx restart.

Hi,
Just for the record, I managed to make it work, here's the nginx config:server { listen 80; server_name mydomain.tls; return 301 https://$server_name$request_uri; } server { server_name mydomain.tls; listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/mydomain.tls/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/mydomain.tls/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/ssl/certs/dhparam.pem; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:4567; proxy_redirect off; # Socket.IO Support proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } }Hope it helps someone.
Cheers
Christian
