Can't login in the unity editor!

đŸŒ” Needle Engine

Since the last update, it’s necessary to log into your account in the Unity Editor to use Needle. However, on one specific PC, logging in just doesn’t work. It seems like the server returns an empty response or something similar—when trying to log in, it fails and simply says ‘logged out successfully’. It’s not an account issue, since we can log in fine on other PCs. We’ve also tried multiple different accounts on this machine, but all of them fail. Any ideas?

Hello null,

The issue you’re experiencing with logging into the Unity Editor could be due to a variety of reasons, especially since it works fine on other PCs. Here are a few troubleshooting steps you can try:

  1. Check Internet Connection: Ensure that the problematic PC has a stable internet connection. Temporary network issues could cause login failures.

  2. Firewall/Antivirus Interference: Sometimes, security software can block outgoing requests. Check if there are any firewall or antivirus settings that could be preventing the connection to Unity’s servers.

  3. Clear Unity Cache: Sometimes clearing the cache can resolve issues. You can try deleting the Unity cache located at C:\Users\<YourUsername>\AppData\Local\Unity\cache.

  4. Reinstall Unity: As a last resort, consider reinstalling Unity on the problematic PC. Make sure to back up any important projects before doing so.

  5. Use Safe Mode: Try launching Unity in Safe Mode, which disables third-party assets to see if a specific asset is causing the issue.

Since you mentioned multiple accounts were tried but still failed, it seems to be a machine-specific issue.

If these suggestions do not resolve the problem, you might consider checking the logs on the problem machine for any error messages during the login attempt.

Feel free to reach out for further assistance or to provide more details about the issue!

Hello, can you share which version you currently use of Unity + Needle Engine? And perhaps include any other relevant log messages? Please consider sending a bugreport via the menu item Needle Engine/Report a Bug so we get access to the log files

We are using Unity Version 6000.0.24f1 and Needle Version 4.2.4
When I click the Login Button in the Editor it opens up the Login Window in the Browser.
I succesfully login but somehow it then says that the login failed.
Im not sure if there even are any logs i could provide here.

That sounds odd - You’ll find additional logs in your unity project at Logs/Needle.log and Needle-prev.log. Those will be sent together with the bugreport.

Maybe first try updating to the latest release version which currently is 4.3.2 ?

I opened a new scene, I try login but skiped the 2FA verification. Now everytime I try to login, even if I create a new unit file and reimport the needle engine I get “Login cancelled. You can close this window now”

Hi, this sounds like your browser has still cached your previously incompleted login response (if you didn’t complete the 2FA). Can you try logging out of https://cloud.needle.tools and try again? And/or perhaps try clearing your browser cache or completing the login process in an incognito window.

I get the same Screen as Pavel. When i press login in the unity editor it opens up the Browser. I then login to needle and it brings me to the site: Needle Cloud where it just says: “Login cancelled. You can close this window now”. If i try to press the login button in the unity editor again it now always just immediately opens up this cancelled page and doesnt even ask me to login anymore. the log says:
