Problem with self-hosted server and firefox extension

[xylle]

Helo,

i have a problem with LanguageTool self-hosted server and firefox extension.

My self-hosted server work properly with :

• curl : curl -X POST --header 'Content-Type: application/x-www-form-urlencoded' --header 'Accept: application/json' -d 'text=toto%20est%20le%20bienvenue&language=fr-FR&enabledOnly=false' 'http://languagetool.example.org/v2/check'
• Brave with this url : http://languagetool.example.org/v2
• Thunderbird with this url : http://languagetool.example.org/v2

Is not the real url, server url is resolvable only with my local dns

But with firefox, i have un error message and no connection log in apache and no connexion in browser network tab. I try with new profile with only LanguageTool extension.

Connexion au serveur http://languagetool.example.org/v2/check impossible — veuillez vérifier votre connexion internet ou réessayer dans quelques minutes (#1, code=0)

deepl translation :

Unable to connect to the http://languagetool.example.org/v2/check server - please check your Internet connection or try again in a few minutes (#1, code=0)

Version :

• LanguageTool server : 6.5 stable
• java : openjdk-17-jre-headless:amd64 17.0.14+7-1~deb12u1
• Firefox : 128.6.0esr
• LanguageTool Firefox addons : 8.14.3

Isn't a CORS issue?

Try docker and check if this helps. I couldn't test it yet, but... Who knows?

Sorry, i dont have docker, i dont try.
I have add this to apache :

<VirtualHost *:80>
	<IfModule mod_headers.c>
	  Header set Access-Control-Allow-Origin "*"
	</IfModule>
	ServerName languagetool.example.org
	ProxyPass / http://localhost:8081/
    Loglevel    info
    ErrorLog    /var/log/apache2/languagetool.example.org.err.log
    CustomLog   /var/log/apache2/languagetool.example.org.log "%{%Y%m%d%H%M}t|%h|http://%v%U|%s"

</VirtualHost>

Systemd unit :

[Unit]
Description=LanguageTool server
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/java -cp /srv/LanguageTool/LanguageTool/languagetool-server.jar org.languagetool.server.HTTPServer --port 8081 --allow-origin "*"

I have no trace in network panel and apache log

It's this issue, I guess? languagetool-org/languagetool-browser-addon#279
