When playing in the editor WebSocket (from Runtime/Online/WebSocket) connection was successful but failed when playing in packaged project. Why? UE4 versions used were 4.18 and 4.19. Platform is Windows x64. Here’s the log. ``` [2018.10.23-08.55.37:666][308]LogTemp: Display: Connecting to wss://localhost/lobby/ [2018.10.23-08.55.38:397][350]LogWebSockets: Warning: Lws(Error): server's cert didn't look good, X509_V_ERR = 20: error:00000014:lib(0):func(0):SSL lib [2018.10.23-08.55.38:431][352]LogWebSockets: Warning: Lws(Error): server's cert didn't look good, X509_V_ERR = 20: error:00000014:lib(0):func(0):SSL lib [2018.10.23-08.55.38:443][352]LogTemp: Display: Error connecting: Connection timed out ``` Upon closer examination, the UE4’s WebSocket library uses Libwebsocket and OpenSSL, and that `X509_V_ERR = 20` means `X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY`. [See here.](https://github.com/openssl/openssl/blob/master/include/openssl/x509_vfy.h#L119) But I’m sure the certificate is valid, and not self-signed. Can anyone help? Again note that the connection works in the editor but not in packaged project. I’m not sure why. In 4.20 the log is like this ``` [2018.10.23-13.28.59:390][399]LogTemp: Display: Connecting to wss://localhost/lobby/ [2018.10.23-13.29.00:119][446]LogWebSockets: Warning: Lws(Error): SSL error: unable to get local issuer certificate (preverify_ok=0;err=20;depth=3) [2018.10.23-13.29.00:121][446]LogWebSockets: Warning: Lws(Error): SSL connect error 336134278: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed [2018.10.23-13.29.00:122][446]LogTemp: Display: Error connecting: lws_ssl_client_connect2 failed ``` Basically the same error, but more verbose. ---

Sigh, turns out UE4 doesn’t automatically copy the certificate file into pak file. Also the SSL module really lacks documentation, but I figured it all out eventually.

Something else to check depending on the platform you’re targeting, make sure that platform is setting WITH\_SSL to 1 and including the necessary include paths and third party libraries in SSL.Build.cs. Otherwise, code that you’ll need will not be included in your build causing all sorts of issues. If your platform isn’t listed in SSL.Build.cs,you’ll need to add a new line like so: ``` Target.Platform == UnrealTargetPlatform.YourNewPlatform ``` Good luck! ---

For anyone else looking, VE1977’s comment below solves it. The exact steps to fix it is: 1. Copy [Engine directory]/Engine/Content/Certificates/ThirdParty/cacert.pem to [Project directory]/Content/Certificates/cacert.pem 2. In your project settings, under Packaging, add an array item to “Additional Non-Asset Directories to Package”, with the value Certifications That’s it, no need to do anything in C++. You may need to copy this again when you update engine version. ---

Hi. Suggested solution does not work on my PC. Do anyone know if there is any other way of fixing certificate? And just to be sure. Does this fix also helps with editor behaviour or its only for packaged build? Thanks! EDIT: Found this forum entry.

Hi. We got something similar to this on one of the machines at our company. For that specific one, all HTTP requests were blocked by one request failing; more specifically, the usage tracking request of the ExpressiveText plugin. So it’s worth checking the logs and looking for warnings about the HTTP module processing requests. Disabling the plugin worked. ---

I just want to say thank you for this thread, it saved us A LOT of time! We had issues with a third party plugin not able to perform SSL verification on cooked builds on MacOS and UE 5.3. The solution for us was settings those certificates as RuntimeDependencies for the plugin, so after cook, those non USF files will be staged with the build. That being said, the other mentioned solutions can possibly work as well.
