Show "Jatos local" after configuration of Apache as a proxy
Hi there,
I've deployed Jatos on an AWS server, with Apache2 as the reverse proxy and SSL encryption. Since it is actually a local installation (because the binding port is localhost:8080), the GUI for my https:/[our domain name]/jatos show "Jatos local" on top, as it is shown here (https://www.jatos.org/Deploy-to-a-server-installation.html ), which mentions that "A local JATOS installation has a black bar on top. A server installation has a light-grey bar."
When I generate links for a study, they are all like this
https://localhost:8080/publix/GI2kz1qlkio
If I replace localhost:8080 with [our domain name], I can open the correct study webpage, but I need to replace "localhost:8080" for all links generated if I want to send them to participants.
Since I use reverse proxy, I think it is supposed to be set as local. But is there a way to make it like a real server installation?
I'm using an AWS EC2 Debian 11 instance;
In the production.conf, the IP and port are set as:
play.server.http.address = "0.0.0.0" play.server.http.port = 8080
After I start jatos, it shows
admin@myserver:~/jatos_linux_java$ JATOS uses local Java Starting JATOS... started To use JATOS type 127.0.0.1:8080 in your browser's address bar
In the /etc/apache2/sites-available/mysite.com.conf, I have:
Let me know if you know how to solve the problem or you need more info!
Thank you very much!😀

Hi Sheng,
I just tried it with JATOS version 3.7.4 on my machine and it worked. I can't see any obvious problems in your config.
My config is:
and
$ cat /etc/apache2/apache2.conf <VirtualHost *:80> ServerName www.example.com # Redirect all unencrypted traffic to the respective HTTPS page Redirect "/" "https://www.example.com/" </VirtualHost> <VirtualHost *:443> ServerName www.example.com # Restrict access to JATOS GUI to local network #<Location "/jatos"> # Order deny,allow # Deny from all # Allow from 127.0.0.1 ::1 # Allow from localhost # Allow from 192.168 #</Location> # Needed for JATOS to get the correct host and protocol ProxyPreserveHost On RequestHeader set X-Forwarded-Proto "https" RequestHeader set X-Forwarded-Ssl "on" # Your certificate for encryption SSLEngine On SSLCertificateFile /etc/ssl/certs/apache-selfsigned.crt SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key # JATOS uses WebSockets for its batch and group channels RewriteEngine On RewriteCond %{HTTP:Upgrade} =websocket [NC] RewriteRule /(.*) ws://localhost:9000/$1 [P,L] RewriteCond %{HTTP:Upgrade} !=websocket [NC] RewriteRule /(.*) http://localhost:9000/$1 [P,L] # Proxy everything to the JATOS running on localhost on port 9000 ProxyPass / http://localhost:9000/ ProxyPassReverse / http://localhost:9000/ </VirtualHost>And I didn't change anything in JATOS' production.conf. So JATOS port is the default 9000.
Hope this helps.
Best,

Thank you Kristian!
Maybe I can try on another AWS instance.
It is working now! It shows yellow icon on the top bar!
Although I'm not 100% sure, I can share what I did for your reference.
Some files were generated during my configuration of Apache in the directory /etc/apache2/sites-avaibable and /etc/apache2/sites-enabled, which include "mysite.com-le-ssl.conf". I removed that file in both directories and redo the
Maybe this is the solution.
