Hello everyone

I just upgraded Mattermost to the version 3.0.2. It works all fine only that I see in the apache log this:

[23/May/2016:17:56:18 +0200] “GET /api/v3/users/websocket HTTP/1.1” 500

Here is the relevant configuration of my apache:

RewriteEngine On

RewriteCond %{REQUEST\_URI} ^/api/v3/users/websocket [NC,OR]  
RewriteCond %{HTTP:UPGRADE} ^Websocket$ [NC,OR]  
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]  
RewriteRule .\* ws://xxxx:8065%{REQUEST\_URI} [P,QSA,L]

RewriteCond %{DOCUMENT\_ROOT}/%{REQUEST\_FILENAME} !-f  
RewriteRule .\* [http://xxxx:8065](http://xxxx:8065)%{REQUEST\_URI} [P,QSA,L]  
RequestHeader set X-Forwarded-Proto “https”

\<Location /api/v3/users/websocket\>  
Require all granted  
ProxyPassReverse ws://xxxx:8065/api/v3/users/websocket  
ProxyPassReverseCookieDomain xxxx:8065 xxxx

 Require all granted ProxyPassReverse http:/xxxx:8065/ ProxyPassReverseCookieDomain xxxx xxxx

I don’t understand because Apache gives a 500 because i think Mattermost works fine like before. The only thing that I noticed is that the browser takes longer until it gets the status of the other users.

Thanks for your help

Hello,

I was wondering if you resolved this. If so, could you post your answer for us? I have [reported a problem](http://forum.mattermost.com/t/submitting-new-message-remains-gray/1679) that led me to [a configuration that no longer works](http://forum.mattermost.com/t/solved-apache2-reverseproxy-with-websocket-https/437/3). If you got yours working, that would be great.

Thank you

I resolved my issue using [advice from this thread](http://forum.mattermost.com/t/apache-2-4-mod-proxy-wstunnel-https-websockets/863). In essence, It required the addition of the mod\_proxy\_wstunnel. In Jessie, I did it with:

`sudo a2enmod proxy_wstunnel`

For posterity, here’s the working config:

```auto
