Android WebView gives net::ERR_BLOCKED_BY_ORB when loading URL tried solutions didn't help only showing on some URLs
The error net::ERR_BLOCKED_BY_ORB
is related to a request that breaks CORS.
There is this Google group conversation that mentions that a change happened in Chromium:
Handle ORB network errors as DevTools issues
ORB "v0.2" changes error handling from silently injecting an empty response to raising a network error. Since the default is to log errors on the console this can lead to a very "spam-y" console. To resolve this, we will always report ORB network errors (ERR_BLOCKED_BY_ORB) to DevTools as an issue, and will suppress console messages for the same errors.
I would suggest making sure that the original url that is loaded within the webview has the same domain as the url that is giving you this error.
