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.

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.

Recently I have received the following message when I try to access some web sites;

we could not verify the certificate: reason = wrongHost

What is going on here and how do I fix it?

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?

Hello, This is Fr. Sakala, a Catholic priest. I have been trying to re-log in a regular site, hyella.com.ng, but could not access it.

Secure Connection Failed

An error occurred during a connection to lius.myloweslife.com. Peer reports it experienced an internal error.

I encountered a problem: when trying to open the Prohoster.info website on my computer, a notification appears that the connection is not secure. I don’t understand how to fix this error and what needs to be done to gain access to the hosting?

Why is access to this site being blocked all of a sudden? I have been subscribing to this online newspaper for decades, and now within the last month I cannot load the page because of a security problem. Why is this happening? There is nothing wrong with the site.
