Hi everyone: I am new using Openziti. When I create ziti admin console and run following code, it shows some errors. Could could please share some idea to solve it? Thank you very much user@user-virtual-machine:~/.ziti/quickstart/user-virtual-machine/ziti-console$ node "${ZITI\_HOME}/ziti-console/server.js" node:fs:590 handleErrorFromBinding(ctx); ^ Error: ENOENT: no such file or directory, open '/home/user/.ziti/quickstart/user-virtual-machine/ziti-console/dist/ziti-console-lib/assets/templates/header.htm' at Object.openSync (node:fs:590:3) at Object.readFileSync (node:fs:458:35) at file:///home/user/.ziti/quickstart/user-virtual-machine/ziti-console/server.js:84:17 { errno: -2, syscall: 'open', code: 'ENOENT', path: '/home/user/.ziti/quickstart/user-virtual-machine/ziti-console/dist/ziti-console-lib/assets/templates/header.htm' } user@user-virtual-machine:~/.ziti/quickstart/user-virtual-machine/ziti-console$ npm -v 8.19.4 user@user-virtual-machine:~/.ziti/quickstart/user-virtual-machine/ziti-console$ nodejs -v Command 'nodejs' not found, but can be installed with: sudo apt install nodejs user@user-virtual-machine:~/.ziti/quickstart/user-virtual-machine/ziti-console$ node -v v16.20.2 user@user-virtual-machine:~/.ziti/quickstart/user-virtual-machine/ziti-console$ ---

Hi @Jheng, did you follow the ZAC quickstart exactly as outlined? That looks to me like somehow the "build the angular app" step was missed? Did you maybe pull recently and miss that the app build process changed slightly? ![image](https://global.discourse-cdn.com/free1/uploads/netfoundry/original/2X/c/c4e370e8246cdf139af5af4ce9367a7083e6aecd.png) Did that succeed for you? @rgalletto fyi ---

You need to read the error messages more closely. It looks like you have permission problems? ```auto npm ERR! The operation was rejected by your operating system. npm ERR!

Yes,I'm just checking again to see if it's a permissions issue. Because I added sudo before, it was ok. punycode module has been deprecated How should I correct him? ---

it's up to you as to the proper way to correct it... if it were me, I'd probably remove the cloned repo, reclone it and try again. but you can chmod it if you want, there are lots of ways. I don't think I can tell you "the one way" to do it ---

Based on the console logs, the ZAC server should be up and running. If you try to access the console via `http://` on port `1409`, or `https://` on port `8443`, I expect you should be able to login. There does appear to be a minor bug in the startup script for `server.js` which is what is causing the error logs you're seeing. Basically, if the server has to retry starting on a different port than the default (ie. `1408` -\> `1409` based on your logs) it will also retry the TLS port again as well. Since the server was already able to initialize on `8443` the first time, it then threw an error on the second attempt since the address was already in use. We'll get this retry logic cleaned up, but in the meantime your ZAC should hopefully be up and running. Let us know though if you're still having issues. ---

> After reinstalling and running server.js, the following situation occurred. @Jheng also just one other question.. do you still have a previous instance of ZAC running already? Or maybe another program that's running on port `1408`? If so, you might also want to try shutting the other instance down first before running the latest.
