Hi @Legion112 ,

I’ve already consulted with our devs and they have a few suggestions here, could you please try the following options on your side:

1. Renew the certificate on your PC: the mentioned errors could be related to the old certificate version;
2. Run the same CLI commands using another PC or laptop;
3. Run the CLI from the same machine, but fully change the directory and path (as the example: run CLI from another local disk instead of the current one, because there is a chance it’s connected with disk permissions);
4. Connect to another network and try to run the same command;

By the way, could you please also tell us if you’ve tried any option suggested in the following discussion thread? https://stackoverflow.com/questions/21076179/pkix-path-building-failed-and-unable-to-find-valid-certification-path-to-requ

Looking forward to your reply,

Out of the blue, I got stuck with this again:

Initialization Crowdin Cli failed. Please check your configuration file and credentials.

A debug run (java -jar "/usr/lib/crowdin/crowdin-cli.jar" upload --debug) revealed:

com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Diving into the issue it turns out that Pihole is blocking api.crowdin.com:

So make sure to put it on your whitelist.
