Hi @ninjabadgerpirate - are you sure you are setting the environment variable correctly? Setting it should disable all cert checks, including the one you are seeing. A common issue is using the set
command within Powershell. This has no effect. The set
command should only be used in a cmd prompt. In Powershell, you would set it like this
$env:NODE_TLS_REJECT_UNAUTHORIZED=0
Also, it should be possible to resolve it properly even if there are no intermediate certs. Assigning your public internal CA Cert to NODE_EXTRA_CA_CERTS should work. For a more details explanation on cert handling, you can have a look at my conference session: https://youtu.be/gpT8uieBqX0
Firstly, thank you so much for your prompt response - I really appreciate all the work that you have already done on this module. Your suggestion was correct and has resolved the issue I was experiencing with SELF_SIGNED_CERTIFICATE, but now I think I am dealing with a similar issue to what has been outlined here:
When I try to connect to my QA SSO server, I get a 401 Unauthorized error, even though I have confirmed that the credentials that I am using are correct (My SSO server is hosted in IIS 10 which seems to line up with the issue linked above) I have tested the same request against a locally hosted version of the SSO API, and it works as expected.
I have enabled debugging in my application, and I am seeing the following error:

I have searched online and it seems to suggest that HPE_INVALID_CONSTANT means that the response is malformed in some way: https://stackoverflow.com/questions/34769824/what-does-this-error-mean-hpe-invalid-constant
I haven't seen this specific error before, but as you already found it indicates that the response is malformed. The response in question is the response from server (not from the plugin). Since the logs are a bit redacted I cannot see what server that response came from, but if you are only communicating with mysso.domain.com it would be from there.
From just decoding the raw buffer content it doesn't look invalid (the bytes in the log represent this:
HTTP/1.1 504 Gateway Timeout
Content-Type: text/h
Likely the root cause of the parsing error occurs later in the buffer - it could be that the content length is not defined correctly. Either way, the response is a 504 Gateway Timeout, signaling that the server is trying to act as a proxy and could not get a response back in time.
Does that help? I think I need to know more about your network and server setup to be able to help more.
504 gateway timeout definitely means that the proxy is causing some kind of an issue. I am integrating this solution behind a corporate proxy, so I am pretty sure that the Proxy is causing this issue.
I have set my HTTP/HTTPS_PROXY/NO_PROXY environment variables and I see that the values are being reflected in the Cypress UI under Settings -> Configuration, however no matter what I try setting my NO_PROXY settings as, I cannot change the values that show up under Settings -> Proxy Settings:
The Proxy Server http://127.0.0.1:57942 is the value set by Cypress NTLM as the ntlmProxyUrl. The Proxy Bypass List is always set to <-loopback> which I understand forces all traffic for localhost to run through the proxy. I am trying to test an application that is running on my QA server within my network on a custom domain (e.g. myuidomain.com), so the domain is not localhost.
I believe that means that the Proxy Bypass List should include myuidomain.com, but I can't quite figure out how to set it correctly, it always seems to include the <-loopback> setting - can you advise me if I am doing something wrong?
The proxy settings shown within Cypress are set by the plugin. This is how the plugin actually works, it acts as a proxy for Cypress where it can intercept the traffic and handle windows authentication when needed. So <-loopback>
is correct, this is required for the traffic to pass to the plugin.
When you set NO_PROXY before starting cypress-ntlm, it will pick up that setting and use it internally. Then it will pass the <-loopback>
setting along to cypress. So from your description you seem to have set it up properly.
If you enable debug logging, there is some information printed when the plugin modifies the NO_PROXY variable.
Does your corporate proxy require authentication? The plugin does not support that scenario.
Hi bjowes, I haven't ever had to setup authentication with our internal proxy, so I don't think it requires authentication as I have gotten the proxy working with quite a few different tools without having to authenticate. At this point, not really sure what else I can try - I will try enabling debugging and digging through the logs to see if I can see what may be causing the issue.
I have just made a beta version available that will accept (but warn) invalid (such as self signed) certs by default. Please try it out to see if that helps.
npm i cypress-ntlm-auth@4.0.0-beta.1
Hi Bjorn, thanks for letting me know. I will add it to my solution and let you know what I find. Beyond adding to as a dependency is there anything else I should do to enable this feature?
Hi Bjorn, I have added the beta version and I removed the SSL Validation environment variable that I had enabled using: _$env:NODE_TLS_REJECTUNAUTHORIZED=0 but now my authentication no longer works. I am getting the following error:
cypress:plugin:ntlm-auth Removed agent for 127.0.0.1:59867 due to socket.close +3ms

at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:706:12) {
code: 'UNABLE_TO_GET_ISSUER_CERT_LOCALLY'
When I re-run the the following line: $env:NODE_TLS_REJECT_UNAUTHORIZED=0, the authentication works again. Let me know if you need me to try anything different and I will give it a try.
Well, it is in beta for good reason, but I have tested it successfully on my own machine. I will need to test it more on a windows machine. You could double-check that you are really using the beta version, and you could try setting the HTTPS_VALIDATION environment variable to something odd like 'invalid' - that should trigger an error log and would confirm that the code published in the release is indeed the correct one.
Found an issue, just released cypress-ntlm-auth@4.0.0-beta.2
. Please try that instead.
Hi Bjorn, that looks like it did the trick. I no longer have the NODE_TLS_REJECT_UNAUTHORIZED variable set and it my tests executed as expected. Thanks very much for sharing this with me.
Please let me know if you need anything else from me, and I will do what I can to assist.
That's great news! If you would have a look at the docs describing the HTTPS_VALIDATION, and give me a short feedback if it is clear and understandable that would be great. The whole intention of this change was to make it easier - so I want to make it fairly easy to understand the docs too :) Otherwise, just be alert if anything appears to behave strangely with the new version. I will likely go to stable if there are no new issues in the coming weeks.
Hello I am trying to integrate Cypress.IO in our environment, and I am getting the following error when calling one of our APIs that using NTLM to authenticate the client's identity.
PROXY_TO_SERVER_REQUEST_ERROR on /api/v1/Account: Error: self signed certificate in certificate chain at TLSSocket.onConnectSecure (_tls_wrap.js:1497:34) at TLSSocket.emit (events.js:315:20) at TLSSocket._finishInit (_tls_wrap.js:932:8) at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:706:12) { code: 'SELF_SIGNED_CERT_IN_CHAIN' } Destroying client socket. +18s
The API has an SSL associated with it, but the certificate has been issued by my company's internal networking team. I suspect that because of this, and the lack of a "real" intermediate authority the SSL is being seen as a self signed certificate. Is there anyway I can get cypress-ntlm to accept these self signed certificates?
I tried running the following command:
set NODE_TLS_REJECT_UNAUTHORIZED=0
And this did not resolve the issue. I tried converting the SSL Certificate into a .cer fle and using this line in the hopes that it would allow the SSL to be correctly validated:
set NODE_TLS_REJECT_UNAUTHORIZED=0
But it didn't seem to do anything. I really want to use Cypress.IO, but this issue is currently a blocker for us adopting the tool. Any help you could offer me would be greatly appreciated.
