Detox can't seem to connect to the test app(s)!

[vauruk]

Did you test using the latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test fail and you're not sure why?

• I have read the troubleshooting guide and it didn't help me.

What happened?

I saw all the issues here but anyone help with this problem however can't be fixed my problem. I can run on iOS platform, but in Android I can't, and I'm in this problem for many days. Can anyone help me with this, please?

Thanks @vauruk for reporting this issue. I am also getting exactly the same issue. Any update?

[vauruk]

No, @uasghar-smile I haven't found an answer, and I've looked into all the look problems, but I can't fix this.
