Error related to SSL/TLS version

Hi All,

I have created HTML5 extension for InDesign CC 2017 and CC 2018.

The extension makes GET request to communicate with the server and get the required data.

a. In case of CC 2017, GET request fails with ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

b. In case of CC 2018, works fine.

I looked further into this and my findings are,

- HTML5 extensions are hosted in embedded version of Chromium (Google Chrome).

- CC 2017 uses Chrome version 41. Chrome 41 supports TLS version 1.2 (and previous versions).

- CC 2018 uses Chrome version 57. Chrome 57 supports TLS version 1.3 (and previous versions).

The server that the extension connects to supports TLS 1.2, therefore Chrome 41 (CC 2017) should work fine. Do I need to make any change for CC 2017? Please advise.

Regards,

Narayan

The error ERR_SSL_VERSION_OR_CIPHER_MISMATCH appears due to a lack of “common SSL protocol version or cipher suite support” between a web server and a user’s browser. This issue happens during the TLS handshake process. With that, the browser will automatically display this specific error message. There are many different reasons for the error to be occured and also many methods to solve the error which should be understand in detail. Hope it helps!

Hi Narayan,

Sorry about the delayed response time.

Have you seen this Chrome compatibility chart in the documentation? It might be helpful.

Generally speaking, if this is a CEP problem or an InDesign problem, and it's fixed in the 2018 versions, usually there's not much you can do about the problems in 2017.

That said, I'll also ask the the teams about your issue.

Best,

Erin

Hi Erin,

Thanks for the reply.

Yes I have seen the CEP/Chromium chart in the given link. CC 2017 uses Chrome version 41 (CEP 7.0) which supports TLS version 1.2 (and previous versions).

I looked further into this by downloading the CEF client and testing the web service. And get the same error.

Narayan
