I'm trying to build with Ionic 6 behind a proxy. So far I haven't had any connectivity issues, but...
I get the following error:
Exception in thread "main" java.io.IOException: Downloading from https://services.gradle.org/distributions/gradle-7.1.1-all.zip failed: timeout
I will appreciate if you can help me, I am stranded with this, thank you very much

I have a project on ionic 2, which I have not touched for 3 years, but the client is asking me to change a simple link. And I can not build the application. What should I take into account to recover this project?
I do not want to migrate to ionic 3 or ionic 4, I just want to change the webservices link and that the application continues in ionic 2.

Is it possible to build this old project on ionic 2 on my computer?
EDIT:
when sudo ionic cordova platform add android i get:
`(node:41668) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Failed to fetch platform cordova-android#7.0.0
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

u should install Cordova first, like this,use # plus version number as needed
npm install -g cordova
I developed an app that was working perfectly on Ionic DevApp on my iPhone. Suddenly it stopped working. I even tested a new blank app and it does not work. I tested on many wifi and 3G signals and also on an Android phone but it does not work!
On my iPhone I’m getting the following error:
Unable to load page. The request timed out.
On the Android phone I got this error:
error err_connection_timed_out.
I tried running the following, but none worked:
ionic serve
ionic serve -c
ionic serve -c --no-proxy
Running ionic info gives me:
Ionic:

EDIT:
I tried running ionic repair which gives me this error:
shell.js: internal error
Error: ETIMEDOUT: connection timed out, read
[ERROR] An error occurred while running subprocess cordova.
cordova prepare exited with exit code 1.
It was just a Firewall coming from McAfee Firewall blocking the port I needed. Just had to open the port on the McAfee app.
When i used ionic serve it throws some error even though I tried many solutions like (solution 1,solution 2,solution 3) but nothing was worked and i mentioned my error below
events.js:183
throw er; // Unhandled 'error' event
^

My ionic 3 project run OK with ionic cordova run android; however, if I added the --prod flag, i.e. ionic cordova run android --prod The process hangs without any errors. The following is where it stopped:

Please help! Thanks...
Try command
ionic cordova build android --prod --release
Any one still having this issue, a big cause of this problem is PLUGINS
run ionic cordova plugin
And have a look at your list of plugins, and uninstall All the dodgy ones, and those you arent SURE are working by running ionic cordova plugin rm your-plugin-name
This is the problem 98% of the time.
