React-devtools: devtools cannot connect

[Char-set]

Why doesn't it connect

[fmorato]

I Also can't get it to connect to react native app. Could not find any information about it.
Using react native 0.50.1 and react 16.0.0 on linux. Tried with local and global installation of react-devtools 2.5.2. Tried with device plugged through USB and over Wifi. Also changed the port in the In-app dev settings to 8097 but it didn't work. I guess that's only for packager.

Running adb reverse tcp:8097 tcp:8097 made it to work with connected device. :) probably works for simulator as well.

Is this a new issue caused by RN update? We'd need more details.

I was having the same issue (in my case running an android virtual device) until I run @fmorato's solution, which should be marked as valid.

Windows 10 Professional
react-native: 0.54.0
react-devtools: 3.1.0

React DevTools has been rewritten and recently launched a new version 4 UI. The source code for this rewrite was done in a separate repository and now lives in the main React repo (github.com/facebook/react).

Because version 4 was a total rewrite, and all issues in this repository are related to the old version 3 of the extension, I am closing all issues in this repository. If you can still reproduce this issue, or believe this feature request is still relevant, please open a new issue in the React repo: https://github.com/facebook/react/issues/new?labels=Component:%20Developer%20Tools
