I am trying to access static IP addresses on my Intranet. I could in the past type in the IP address and I would get a notice that the site is not secure and allow me to continue to the site. Now it tells me that the website cannot be reached. I need to get to the GUI interface of cameras on my network. How do I get this to work?

All of a sudden almost every site I try to enter comes up with "Secure Connection Failed". This started happening on Friday, July 10th for the first time. I've read almost every article in the Firefox's community forums and tried multiple actions and nothing stops this. I don't know why this all of a sudden when it never did this before. I hope someone can tell me how to stop this from happening].

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with ebanking.bankmellat.ir. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

ebanking.bankmellat.ir has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

I am getting more frequent "Firefox can’t create a secure connection to the server " messages. This isn't inherently an issue, but on most of them there is no longer a "continue anyway" button. I know your first response will be "It's for your safety." Well now, I'm a big boy, 58 to be exact, and I wear my big boy pants everyday. I am perfectly capable of deciding how much risk I'm willing to accept. This especially applies to sights I am familiar with and trust that suddenly trigger your warning for some mysterious reason. This is becoming a large problem for me and if there isn't a fix for it I may have to reconsider my use of Firefox.

Hello!

For few minutes it says "Performing a TLS handshake to youtube.com", then this message appears:

==

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

==

What I did so far:

1. Deleted cache and site data for youtube.com. 2. Checked if date and time setting is set to auto and synced it just in case. 3. Tried restarting firefox in safe mode. 4. Tried turning off ocsp stapling. 5. Deleted ALL cache and site data. 6. Tried creating a new profile. 7. Set HTTPS-only mode to "don't enable" and added youtube.com to exceptions

I do use DoH. I can't not use it. YT won't work without it for sure. Provider is google: https://dns.google/dns-query

Everything works fine in Chrome (yes, I use DoH there too).

My virus program is sedning me this message.

firefox.exe attempted to establish a connection relying on an unmatching security certificate to email.squarespace.info. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

How do I stop firefox from contunally reaching out to this web site.
