# SSL Remote Certificate Failed Verification

How to resolve the SSL Remote Certificate Failed Verification error during ENERCALC SEL activation.

If you received this message:

"The SSL Remote Certificate Failed Verification - contact your IT team re: this webpage:

<https://media.enercalc.com/faq_help_20/index.html?ssl-remote-certificate-verific.htm> (webpage address was placed in your clipboard)"

... please report it to your IT team and contact ENERCALC.

**IT team:** This message often indicates that your network is doing packet introspection. When this is done, the packet is re-encrypted before it is sent to our server - but our client-side software does not typically have the CA root certificate for the certificate used to re-encrypt the packet.

The usual solution is to append your network infrastructure's CA root certificate to the existing caroot.pem at C:\program files (x86)`\ENERCALC_20\caroot.pem. IMPORTANT`: This file already exists. You will be appending your infrastructure's CA root certificate text to the end of the existing caroot.pem as an additional certificate.

If you send us your CA root cert, we can add it to the .pem we distribute with the software. Some companies do not wish to do this. If that fits your situation, you'll need to manage adding the root cert to our caroot.pem after each installation / update.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/sel-faq/setup-and-licensing/installation-activation-lice/troubleshooting/ssl-remote-certificate-verific.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
