What is a Certificate?
A certificate is essentially a badge provided by a third party that verifies that the page you are trying to access is legitimate. Without a certificate, a third party can easily "spoof" a website to steal personal information. Using HTTP instead of HTTPS opens your data and browsing to a wide variety of easily preventable attacks.
Below are errors that usually appear in Firefox or Chrome.
Possible Errors
Bypassable Errors
Some errors can be bypassed by going to Advanced → Proceed to Website (unsafe). For these errors, it is not recommended to proceed, as any information or forms you enter can be easily intercepted.

Currently, the only bypassable error is: NET::ERR_CERT_CONTAINS_ERRORS |
Non-Bypassable Errors
Most SSL errors in browsers are non-bypassable, meaning it is up to the site owner to fix the SSL certificate.
Workarounds for Non-Bypassable Errors
It is possible to fix this in some cases by doing the following:
- Clear the Cache in Web Browsers.
- Manually enter HTTP://site.com.
| Note |
|---|
| Most sites use HTTPS redirect, which means they will force you to use HTTPS and this will not work. |
If it is an emergency and you are only attempting to view information (no logins), then it is possible to disable browser security.

List of non-bypassable errors.
NET::ERR_CERT_INVALID - Generic Error
NET::ERR_CERT_DATE_INVALID - The date the website provided was not what the cert authority had on record, so it can't be trusted.
NET::ERR_CERT_AUTHORITY_INVALID - The cert authority the website provided was not who actually issued it, so it can't be trusted.
NET::ERR_CERT_COMMON_NAME_INVALID - The website you are trying to get to is not who the cert authority issued the cert to, so it can't be trusted.
NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED - The certificate requires transparency, but the one provided did not match up, so it can't be trusted.
