Local Computer Does not Recognise Lets Encrypt SSL Cert

Help
#1

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

I ran this command: On my local computer I cannot access my site because it is saying the site is unsecure and that the certificate is invalid. On external computers the site is fine. Just that I can't access my wordpress site on my home computer. This means that I have to use an outside comptuer via an internet cafe to modify my own site. Should I delete the Lets encrpt certificate from the site. I am not sure why my home computers are not recognising the certificate.

It produced this output: Certificate Invalid

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: www.cloudways.com

I can login to a root shell on my machine (yes or no, or I don't know): No

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): - can't access backend on my computer as it says site is unsecure

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Welcome to the Let's Encrypt Community, Diane :slightly_smiling_face:

I have run various tests on your website and found the correct certificate chain being served and no mixed content. Try clearing the cache of the browser on your local computer.

Uh... why?

Hi Griffin,

I have tried this and deleted all browser history from the browsers I was using but it is still the same. If I ignore the warning and go to the site on my local computer the site has not been updated - it is as if everything was 'frozen' and none of the updates I have made via external comptuers have been made. On external computers I can access the site and backend with no problem to update.

Does this happen with ALL browsers on your local computer?

yes, even when I choose to go incognito.

It sounds as if you're getting a cached version of your website from outside. Have you made a content change (like an image or sentence) and not seen the update on your local browser?

I'm wondering if you're using a proxy of some kind from your local machine...

Hi,

Yes, at first I would make updates via wp-admin on my local site but the updates would not show when I checked via the browser.

If I make updates via an external computer the updates show on all browsers. I got to admit this has stumped me but now with the lock down, can't access computer cafes so at the moment stuck. I am thinking should I delete the certificate and reinstall again?

Your certificate is working great. I verified it several different ways.

I'm a bit confused though. What do you mean by "local site"? This makes it sound like you have unpublished changes.

Just a note:
You have HSTS enabled so most browsers will only attempt https requests once they become aware (via the STS header).

I meant local computer. Cloudways support say that perhaps my computer does not recognise the certificate so they sent me a copy of the certificate named after my site which I have uploaded to the trusted root directory of my computer.

On Mozilla I get a message: uses an invalid security certificate.

The certificate is not trusted because it is self-signed.

Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

View Certificate

When I go to the site, changes which I made weeks ago show but since then I have updated the site via external computers. Basically the site I see on my home computer is not what someone outside would see. They would see a fully updated site with no security issues.

Oops, I meant the last set of changes which i made weeks ago on my local comptuter are still there. No udpates, however on external comptuter recent updates have been made.

That's probably the default certificate from the hosting provider. How old is your Mozilla? I'm wondering if it doesn't support SNI. That doesn't explain the content difference though.

Hi,

I just installed new version today. Not sure what to do. I think this is def. a problem with my computer which does not recognise the certificate when I enter the url of my site on any browser on the internet on my home computer.

Hi all,

I have not really launched my site because of the issues which is why I did not include the www especially as this is about the SSL certificate.

Are you fully signed-out of WordPress admin when you access the site?
