Greetings.

Several times today I have had messages not sent because of this error message: "Did Not Connect: Potential Security Issue". I am sending political messages and am concerned that Mozilla is blocking me. I have sent hundreds of similar messages over the years with no problem.

What's up now?

Thank you. Sincerely, Gail Forrest

I am trying to log into a "http" website forum, of which I am a member and I am unable to do so, I think due to my Mozilla and or DuckDuckGo "Settings". If at all possible, I would like to reset my browser settings, so that I am able to rejoin this forum. A step by step reply would be much appreciated, because I am not a fluent user/programmer! This is the "Error" that I am consistently being shown: "Secure Connection Failed An error occurred during a connection to www.motoscrubs.com:80. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG 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." The forum website does not use the "https" address as it does not trade and the extra cost for this type of domain would be prohibitive to its continued maintenance. Thank you for your time. BillR

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

Hello,

I am in a situation where I am a student at the university of Gothenburg. At the university the students have their own spaces at a cyberspace cloud storage facility. The place is called Canvas. In Canvas the students subject are lined up and information about each subject is also stored and other features about the students education. The place is only about university information and education. Yesterday, I tried to log in to my account into Canvas at the university of gothenburg, at Handelshögskolan on my computer. It was not a success. I tried to use the regular webbrowser for Apple, Safari, but it was not a problem there and I was able to login. I was also able to login to my account on my cellphone, which is logged in via an application downloaded from Appstore.

I do not wish to use Safari because it is not purposeful in the usage in the direction via education that i am looking to achieve.

How can you help me solve this please?

Intermittent “SEC_ERROR_OCSP_INVALID_SIGNING_CERT” error on my site in Firefox

Hello, I run a movie and drama-related website: https://tvmon.com.co/. Recently, I’ve noticed that Firefox occasionally throws the following error when trying to access the site:

"Secure Connection Failed An error occurred during a connection to tvmon.com.co. . The OCSP response contains an invalid signing certificate. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"

This issue is very strange because:

  1. The site loads fine in Chrome, Edge, and Safari.
  1. My SSL/TLS certificate is valid, up-to-date, and passes external tests (SSL Labs, etc.).
  1. The error only appears occasionally in Firefox, refreshing sometimes fixes it, sometimes not.
  1. Hosting and server logs show no issues at all.

I suspect this is related to Firefox’s stricter OCSP validation, but I’m not sure how to debug or resolve it. Since my site streams drama and movie content, this error is frustrating for users who rely on Firefox.

Has anyone else experienced this intermittent OCSP signing certificate error? Is there a known fix or workaround for Firefox-specific validation issues?
