I have formatted my android phone - this was working before perfectly.
I have my code in my mac book - and I do "yarn run build && concurrently “yarn run watch” “yarn run start”
on the expo app version 2.6.4 on Android phone version 6.0.1
I get error on expo app: java.net.ConnectException failed to connect to localhost/127.0.0.1:19000 after I scan QR code.
I saw solutions online, but are mainly with windows or disabling firewall - I am unable to find same options in my kind of setup. Please help
When you run the
yarn run start, what is the URL that Expo prints out to use (right under the QR code)?
For me, for example it’s:
[09:50:41] Your URL is: exp://192.168.83.210:19000
If your URL is something like
127.0.0.1, try running
yarn run start with
--lan option and then scan the QR code (run
exp start --help to see other options):
-m, --host [mode] tunnel (default), lan, localhost. Type of host to use. "tunnel" allows you to view your link on other networks
--tunnel Same as --host tunnel
--lan Same as --host lan
--localhost Same as --host localhost
Running the packager with
--lan option makes the packager use not
127.0.0.1 (https://en.wikipedia.org/wiki/Localhost), but some other URL that is more likely to be accessible by your phone, if they’re connected to the same network.
