[Q] Websocket issue 404/502/426 [Solved]

First of all I have to mention I am a novice when it comes to advanced network troubleshooting and solely use google to track down issues whilst attempting to perform fixes. After spending the last two days troubleshooting I finally gave in and decided to ask for help.

So first of all the guide which I have followed is the docker guide at https://docs.taiga.io/setup-production.html#setup-prod-with-docker & launched taiga using the directives on https://github.com/taigaio/taiga-docker

Then after confirming taiga did run but not properly I configured the apache vhosts resulting in firstly a 426 (upgrade required) error code, then a 502, a 404 and now a 502 once again for the websockets.

Taiga itself loads up properly but I can not start any projects as then it freezes and reports those errors. I quickly figured out it was the websockets at fault due to the firefox inspector giving me the following errors:

Then after following a number of guides among which:

https://github.com/docker-taiga/taiga/issues/28

I stumbled upon the following guide: https://github.com/sftd/taiga-doc/blob/master/setup-production-centos-apache.adoc which basically explains a whole different kind of setup at which point I simply gave up and decided to ask for help rather then trying to widly guess solutions at this point.

mod_proxy + all other required modules are enabled which I have quadruple checked at this point and I also double checked with chrome at multiple intervals to see if it was a browser related issue.

My current vhost settings are;


<VirtualHost *:80>

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

ServerName taiga.dregora.com
ServerAlias taiga.dregora.com

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]

</VirtualHost>

and https:

<VirtualHost *:443>

ServerName taiga.dregora.com
ServerAlias taiga.dregora.com

Header add X-Forwarded-Proto "https"
RequestHeader add X-Forwarded-Proto "https"

# Logging
LogLevel warn
ErrorLog taiga.dregora.com-error_log
CustomLog taiga.dregora.com-access_log combined

# Reverse proxy configuration
<Location />
ProxyPass http://localhost:9000/
ProxyPassReverse http://localhost:9000/
</Location>

SSLCertificateFile /etc/letsencrypt/live/taiga.dregora.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/taiga.dregora.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateChainFile /etc/letsencrypt/live/taiga.dregora.com/chain.pem
</VirtualHost>

Aside from the above configs I have tried many, many more. Here are the relevant docket-compose.yml settings:

  TAIGA_SITES_SCHEME: "https"
  TAIGA_SITES_DOMAIN: "taiga.dregora.com"
  TAIGA_URL: "https://taiga.dregora.com"
  TAIGA_WEBSOCKETS_URL: "wss://taiga.dregora.com"
  TAIGA_SUBPATH: "" # "" or "/subpath"

After adding in:

<Location /events/>
ProxyPass http://localhost:9000/events/
ProxyPassReverse http://localhost:9000/events/
</Location>

at the https vhost the following is returned in the console:

I look forward to any replies!
