Periodic requests on self-hosted instance ?

Development

Hi everyone,

I’m self-hosting an instance of LanguageTool using a docker container (the one here). After starting the server, I see that I get a post request every 30 seconds:

2025-05-06 10:48:10.247 GMT INFO  org.languagetool.server.LanguageToolHttpHandler Handling POST /v2/check
2025-05-06 10:48:10.258 GMT INFO  org.languagetool.server.TextChecker Check done: 13 chars, en-US, requestId: null, #153, null, 0/1 matches, 11ms, agent:-, sent, q:0, h:1, dH:1, r:153, m:all, premium: false

Is it normal ? (some kind of self ping by the server itself ?). I was concerned at first, since I saw these requests appearing in the logs on my remote server, even though the nginx reverse-proxy was not started yet and the firewall should have blocked everything except for port 22, 80 and 443 (LanguageTool server is on port 8010). So I was afraid I had misconfigured my firewall, but then, running the docker image on my laptop without network access I still see these messages.
Is it normal behaviour ?

Thanks !

Yes, see Strange idle behavior · Issue #47 · meyayl/docker-languagetool · GitHub

Thank you so much. It didn’t occur to me that it was in the Dockerfile, I was looking elsewhere (in the entrypoint.sh).
