### Website URL [https://boosthubsmm.top](https://boosthubsmm.top) ### Error Message Chain issues: Incomplete (SSL Labs gives grade B) ### Other Information Hi, I have a problem with the SSL certificate on boosthubsmm.top. The certificate is from Let’s Encrypt, valid from October 31, 2026 to January 29, 2027, and it is not expired, but the chain is incomplete. The server is only sending 1 certificate and does not send the intermediate, so SSL Labs gives grade B with the error “Chain issues: Incomplete” and on some PCs the site shows as not secure. Could you please reinstall the certificate using the fullchain (the domain certificate + the Let’s Encrypt YR2 intermediate) and restart the server so it serves the complete chain? After that it should get grade A with no warning. Domain: boosthubsmm.top Server: openresty IP: 185.27.134.115 Thanks. ---

Welcome to the InfinityFree community forum! Good to have you here. - Most people answering here are volunteers. They’re often the fastest source of help. Admin (the only staff member) checks in about once a day for issues on our end. - Volunteers can’t see your account or website. Share what you actually see, like error messages and what happens when you try something. That’s more useful than your theory of what’s wrong. - AI tools often get InfinityFree wrong. If a volunteer’s advice differs from what an AI told you, please try the volunteer’s suggestion first. - Solving an issue is a joint effort. Try the suggestions you get and report back what happened. ---

_Beep boop, I’m a bot! I dug through the forum to get you started. I sometimes get things wrong though, so do with this what you will until a human has a look._ What exactly does the “not secure” warning say on the PCs where you see it? I need the browser, the Windows version and the exact wording or error code, such as `NET::ERR_CERT_AUTHORITY_INVALID`. A missing intermediate normally only lowers the SSL Labs grade. Browsers can usually fetch the intermediate themselves, so a real warning on some PCs might have a different cause. Your chain report matches other recent topics. Those posters also saw only the leaf certificate served on a certificate installed from the panel, and none of them has an answer I can use: > [@SSL certificate chain incomplete (intermediate not sent) - harkus.co.uk](https://forum.infinityfree.com/t/ssl-certificate-chain-incomplete-intermediate-not-sent-harkus-co-uk/121440): > > Hi, On the account for [harkus.co.uk](http://harkus.co.uk), the SSL certificate installed from the panel is served without the intermediate certificate(s): the TLS handshake returns only the leaf certificate (chain length 1). Browsers still load the site because they fetch the intermediate via the certificate’s AIA URL, but strict clients fail with “unable to get local issuer certificate” (curl, openssl s\_client, Python ssl, older devices). Evidence: openssl s\_client -connect harkus.co.uk:443 returns only the leaf… An older topic from 2022 has a reply saying the same thing. It says the platform doesn’t send intermediate certificates, and that modern browsers and operating systems still connect fine, while Qualys grades it down. > [@Server SSL chain is incomplete](https://forum.infinityfree.com/t/server-ssl-chain-is-incomplete/68910): > > Username (e.g. epiz\_XXX) or Website URL epiz\_28730022 Other Information Hi InfinityFree, I am running WordPress on InfinityFree,and I am using the Really Simple SSL plugin. The plugin has a SSL check powered by Qualys. I ran it, and my score was B. I clicked the button that says “View detailed info on Qualys SSL Labs” button to see more info. I saw the page, and I found that the certificate chain is incomplete. By the way, in the page, you can see that DNS CAA… That reply is from 2022, so it may be out of date. I also couldn’t find any source for installing a fullchain on your side or restarting the server. ---

Hi, I would like to add a second domain to this same request: pickdropcuba.shop. It has the same problem — the SSL chain is incomplete, so the site also shows as not secure (red warning). Could you please also reinstall the certificate for pickdropcuba.shop using the fullchain (the domain certificate + the Let’s Encrypt YR2 intermediate) and restart the server so it serves the complete chain, so it stays secure with no red warning? Thanks. ---

I suspect that you may be confusing some issues. To rule that out, can you please share a screenshot of that “not secure” error you get? Because “Not secure” is what browsers show you if you’re accessing a website without HTTPS. That doesn’t mean that HTTPS doesn’t work, it just means you’re not using it. Configuring your website to use and enforce HTTPS is something that must be configured in your website itself, and we have a guide with more details here: > [@How to force all traffic to HTTPS](https://forum.infinityfree.com/t/how-to-force-all-traffic-to-https/49322): > > After you’ve enabled SSL for your website, you’ll probably want to redirect all traffic on your website to the https version of your site. There are multiple ways to do that. Let’s compare some commonly used ways. Using script configuration Some scripts (including Wordpress) have a setting which allows you to set your website URL. By changing this URL from [http://example.com](http://example.com) to [https://example.com](https://example.com), the script will probably redirect visitors to the https version of your site. Even if your script… If my guess is right, then the incomplete CA chain is a red herring, and unrelated to the issue you’re having. > [@Kikito](#): > > Could you please reinstall the certificate using the fullchain (the domain certificate + the Let’s Encrypt YR2 intermediate) and restart the server so it serves the complete chain? After that it should get grade A with no warning. Everything about our service is intended to be fully self service and automated. The only times we’ll actually do anything is if our system is not working as intended, or if we’re reviewing your account for suspected abuse. Installing an SSL certificate for you falls in neither of those two categories. All SSL certificate installation tools are already available to you. If you can’t find it or have trouble using it, we can guide you. But if the controls you want are missing, then that’s what you’ll have to make do with. And as a little aside: our server stack loads SSL certificates on the fly, and doesn’t need to be restarted to apply certificates. It makes no difference to the issue you’re having, but I do want to make it clear that you don’t need to dictate to a hosting provider how they should manage the systems that they have set up themselves.
