When browsing, I sometimes (more often than not) get a Secure Connection Failed message. The Try Again tab clears the problem sometimes (not that often). This problem has just started happening in the last week, during which I have not made changes to any settings in Firefox. This problem does not exist using other search engines for the same site that I am trying to access, and I note that I also get this same failure when trying to access some Firefox webpages. Is there a fix to this other than contacting the web site owner, which I doubt is the cause of the problem, or for ease and simplicity should I just change to another search engine that does not have the problem?

It won't let me connect to websites due to "Did Not Connect: Potential Security Issue" However, I am certain that it's a mistake, because the websites that I'm unable to connect to are https://web.whatsapp.com/ https://www.instagram.com/ and other trusted websites. For youtube it shows that I'm offline, although I'm connected to the internet. This problem may be due to recent issues related to my internet provider and/or router, because I also have issues with discord app as well as some game clients(Jagex, Blizzard, for example).

Reviewing posts pertaining to SECURE CONNECTION FAILED and error code related to that message, one of the suggestions found on-line is to delete any listing from the Certificate Manager that is/may be a problem. However, NONE of those suggestions or discussions makes any mention about "how does one determine which listings those are?"

Relative novice here; was considering whether the "solution" was to merely delete all of the certificate listings, with the hope that the system would then repopulate what was necessary as time went on; some on-line information seems to indicate that to be not a good course of action . . . so my course of action has been to do nothing.

Question remains: how does one determine which listings can be deleted?

Thanks for any clarification.

Hi, I can't connect to my NAS anymore, via private IP. Impossible to add an exception for my auto-signed certificate. Immediate solution : stop using Mozilla. Another one ?

Thanks

I used to be able to connect with Firefox (with a warning message from you) to my local Netgear NAS, but now it just says:

Secure Connection Failed An error occurred during a connection to 192.168.1.100. Peer using unsupported version of security protocol. Error code: SSL_ERROR_UNSUPPORTED_VERSION The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem. This web site might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

How can I still override this with Firefox. It's really important I can connect to my NAS.

With thanks,

Nick Curley

I have been having problems getting access to sites. I keep getting 502 Bad Gateway Certificate verify failed: unable to get local issuer certificate. What can I do? For example, I have been trying to access EFTPS to schedule payments or IRS and get same message. What should I do?

I noticed Firefox sometimes gives extra warnings when using payment gateways on healthcare service websites. Is Firefox stricter with SSL certificates than other browsers? For instance, visit here visit here

and test the checkout security prompts.

Whenever I try to open Github specifically I get:

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for github.com. The certificate is only valid for the following names: cloudflare-dns.com, *.cloudflare-dns.com, one.one.one.one

Error code: SSL_ERROR_BAD_CERT_DOMAIN

I spent time looking into this, used a new IP address and tried updating the certificate for github, however I'm not particularly skilled when it comes to this, so any assistance would be much appreciated.

There are no other sites in which I have this problem with FF x64 DE. In Edge, I see the newsmax pages load while the FF x64 DE https//newsmax.com xontinues to genberate the above message and fails to load the screen.

Please fix.
