Hello, first of all thank for all this good job. and sorry for my English.
I experiment a problem with Traccar 3.3. (other version was running good)
when I access Traccar via http://192.168.5.115:18021 (yes I changed the port ;-) all is good fast and no error. but when I access via my domain name http://gps.****.fr.nf I got lot of bugs.
the domain name arrive on one apache2 with this config :

<VirtualHost *:80>
        ServerName gps.****.fr.nf
        ProxyRequests On
        ProxyPreserveHost On
        ProxyVia full
        <proxy>
            Require all denied
                AuthUserFile  /www/gps.****.fr.nf/.htpasswd
                AuthGroupFile /dev/null
                AuthName "Traccar Acces Restreint"
                AuthType Basic
                require valid-user ****

        </proxy>

        ProxyPass        /  http://127.0.0.1:18021/
        ProxyPassReverse /  http://127.0.0.1:18021/
</VirtualHost>

the bugs are :
-I cannot add an device is giving me a popup with error but this popup is empty.
-I cannot logoff
-and if I logoff then I add an device the device popup is broken.

Edit: i'm on linux64 :
3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

if you need screenshot tell me.

my log are here for fresh install, login with admin, add try to add a device:

Please provide some screenshots with error messages.

Hello Anton, thx for your fast response and your helping. here you have the two screenshot:

here after add an device :
https://app.box.com/s/fypkzkxykuspxsdhx1xd2swmfhr9saii

here after logoff (not come back to login panel) and click on add device :
https://app.box.com/s/4ls6m92wso4lfcmkglpxagj1t9lh7p8w

And sorry for the delay of my response.

Thx.

I would recommend to clear browser cache and see if it helps. Also, check browser developer console to see if there are any errors there.

Hello clear cache not helped. but some errors on debug console :
Firefox ne peut établir de connexion avec le serveur à l'adresse ws://gps..fr.nf/api/socket.
Firefox cannot connect to server at the address ws://gps..fr.nf/api/socket.
the error is in : app.min.js:87:24

Version 3.3 uses WebSockets, so you need to proxy it as well.

hello, hoo ok, then do you have an idea on how forward ws with apache2 server. Coz I try to add this line :
ProxyPass "/ws2/" "ws://127.0.0.1:18021/"
or
ProxyPass "/ws/" "ws://127.0.0.1:18021/"
or
ProxyPass "/api/" "ws://127.0.0.1:18021/"
but no one is working.

can you help me?

thx in advance.

EDIT : I get new error on :
ProxyPass "/api/" "ws://127.0.0.1:18021/api/"
https://app.box.com/s/yhw4ugpmmu0237vzqx5q7982bhz6726g

Please help.

re-Hello, with this :

ProxyPass / ws://127.0.0.1:18021/
ProxyPassReverse / ws://127.0.0.1:18021/
ProxyPass / http://127.0.0.1:18021/
ProxyPassReverse / http://127.0.0.1:18021/

I think is working but still get the device error.
Screenshot

Sorry, and have a good Christmas ;-)

It looks like there is some problem with authorization. I guess proxy doesn't handle headers correctly.

Hello guys,
I do a little up, coz I didn't found any solution.
I have play with some setting in apache 2 conf file but without success.

like :
ProxyRequests On
ProxyPreserveHost On
ProxyVia Full

if any one have the solution or an idea please share it.

Thx.

Are you using "mod_proxy_wstunnel" Apache module?

This also might be helpful (it's for nginx though):

https://www.traccar.org/forums/topic/3-3-and-no-last-position-on-map/

hello,
yes I use "mod_proxy_wstunnel" :
ls /etc/apache2/mods-enabled/
... proxy_wstunnel.load ...
cat /etc/apache2/mods-enabled/proxy_wstunnel.load

Depends: proxy

LoadModule proxy_wstunnel_module /usr/lib/apache2/modules/mod_proxy_wstunnel.so

I will try to force http version to 1.1 like in ngix conf file and this option (but I don't know equivalent in apache then I will search)
proxy_set_header Host $host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_buffering off;
proxy_redirect off;

and maybe the include subfolder in the header.
thx for new way to look for.
I will be back ;-)
