Please help me
I am using iPhone 6 (iOS 10.3.1)
I recently upgraded PRTG(iOS APP Ver 17.2.21) in the App Store.
I can not log in to the PRTG server(Server ver 184.108.40.2067+) after that.
When iOS APP attempts to log in, the following error message window appears
Connection error "Request failed: unauthorized (401)"
What measures should be taken to resolve this issue?
Login is very good on PC and smartphone web browser.
