Getting SocketTimeoutException while converting office file into pdf using JODConverter with Libreoffice running on docker container

Question

I am running Libreoffice in docker container on top of ubuntu:24.04 in headless mode. And running a Java Spring Boot server with jodconverter-spring-boot-starter, jodconverter-core and jodconverter-remote of version 4.4.8. But I am getting error: java.net.SocketTimeoutException: Read timed out.

Can you please do let me know how can I resolve the error?

pom.xml

<dependency>
    <groupId>org.jodconverter</groupId>
    <artifactId>jodconverter-remote</artifactId>
    <version>${jodconverter.version}</version>

Code:

private final DocumentConverter documentConverter;

private File convertOfficeToPdf(
            @NonNull final MultipartFile file) {
    final File inputFile = new File("/tmp", requireNonNull(file.getOriginalFilename()));
    final File outputFile = new File("/tmp", "output.pdf");
    try {
        file.transferTo(inputFile);
        this.documentConverter.convert(inputFile).to(outputFile).execute();
    } catch (OfficeException | IOException e) {
        log.error("Failed to convert office file into pdf: message={} ", e.getMessage(), e);
    }
}
