I don't know what I updated or what I did but when I run the ionic serve command it keeps saying "[INFO] Waiting for connectivity with ng...".

Please share your package.json – Adagietto

here is package.json justpaste.it/8zmct – Daddy

Please have a look to this solution, it may resolve your issue forum.ionicframework.com/t/… – Adagietto

or also try this npm run start instead of ionic serve – Adagietto

Thanks for your answer, I tried the steps in the link you shared before. I did extensive research and followed all the logical steps, but it didn't solve my problem. I just restarted mac and it is currently serving. This is the first time I've encountered such a problem and it's really weird. Maybe someone in the future can try to restart their computer if they encounter such a problem. 😳😅 – Daddy

hahaha! Good Luck :) :) – Adagietto

Answer 1

I had the same problem using Ionic 6.

Running either of the following two commands resulted in the error "Waiting for connectivity with ng...":

ionic serve
ionic cordova run android --l

I think this issue occurs due to some network misconfiguration, however none of the above answers worked for me. Rebooting the mac didn't work either.

The only workaround I found was to add the --external option to the commands, that way everything works like a charm again.

For example:

ionic cordova run android --l --external
