We've also seen reports that older Java versions and older operating system versions may not support the ISRG X1 root certificate from Let's Encrypt (see their blog post <https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/>). The solution in both cases was to update the Java version and the operating system packages (like ca-certificates) to recent versions. You may want to check that your operating system patches are current and that your Java version is current.
