New server cert not recognized by firefox

Note: I control the server. The following is noted on the client:

Your connection is not secure

The owner of [myDomain] has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

And yet, an online cert checker states: Congratulations! This certificate is correctly installed.

So, the obvious answer is it's a caching problem. I found 2 cookies from the old domain that I deleted and then cleared the cache. No luck. *Yes, old domain as I now have a new domain. It sees the old cert for the old domain, which I have revoked and deleted with "certbot revoke". Using Letsencrypt on ubuntu 16.04

Thank you in advance for any help!

I use Firefox 63.0 (64 bits). Since 23 oct 2018 I got message "SEC_ERROR_OCSP_UNKNOWN_CERT" when connecting to my bank site LCL. I don't have this issue with Microsoft edge navigator. If I deselect OCS option in Firfox parameter the issue disappear but come back when I select again the OCS option. How this issue can be solve definitively with keeping OCS option ? Is the connection as well secure without this option ?

Recently I was facing an Issue with my Firefox, it was not connecting to webpages after failing to do a TLS handshake with the server, I was suggested to disable IPv6 in my Firefox to solve the issue. I did the same and it works well now. But I'm curious what the risks I took by disabling IPv6 from Firefox.

Hi there,

We have a weird problem with firefox only (not this problem with other web browser like Chrome, Ie or Edge). The problem is that we cannot browse this website at the same time. No problem to browse one website, but going on the seconde one and you will get on 404 error.

Not Found ________________________________________ HTTP Error 404. The requested resource is not found.

Same error for 3 others.

Just waiting few minutes (at least 5min), refresh the second website, it’s working coming back on the first tab (with the first website), refresh and you get the error 404.

This problem occurs only when we are using IPV6 connexion on an HTTPS websites (only on some of ours web sites (https://www.ticpharma.com/home.php, https://www.techopital.com/ https://www.gerontonews.com, https://www.ticsante.com/home.php and https://www.apminternational.fr/). These 5 website sharing the same SSL certificats. It’s a multi domain SSL certificats provide by Gandi.net.

No problem when we use the Firefox PRIVATE windows. No problem when we browse theses websites in http and IPV6. No problem when we browse theses websites in httpS and IPV4. No problem with other browser in httpS and IPV6.

So only problem with Firefox, in IPV6 and HPPS. This problem occurs on multiple computers, with diffrent Anti-Virus, from different location, for different network and ISP provider. So I guess there is a bug somewhere in firefox.

Thanks for your help. Regards.

Hi,

If a website is dual-stacked, Firefox will first try to connect over IPv6 and fallback to IPv4 if it fails. However, Firefox never tries again to use IPv6 if it as fails once. Sometimes this leads to connection error if the connection is intermittent (so IPv6 will fails at the time of the request, but it’s not specific to IPv6, and Firefox will try over IPv4) and if IPv4 is broken at all (e.g. because IPv6 works so nobody notices it). So when the connection comes back, Firefox will be stuck to IPv4 and the site won’t display even if works with IPv6. Even Ctrl-Shift-R doesn’t clear the connection cache.
