500 invalid request code=4

"500 invalid request code=4" means Poweramp can't get reliable connection to Poweramp authorization server, and the request from your device is modified in the middle.

This can be:
- bad connection - packet truncated (please try another wifi connection)
- you're behind some router which requires authorization and redirects to some login web page (please try to open anything in mobile browser first)
- you're behind some firewall/router which modifies http content and inserts e.g. ads in it (please try another wifi connection)
- you're using lucky patcher or similar modified Poweramp apk. No need to do this if you get license, but if you previously modified Poweramp it can be quite hard to revert it back - contact us for help
