PRTG uses an elliptic curve for secure connections that Android N does not support. The required keys for establishing secure connections are not available by default sometimes, especially on older systems. If you still cannot connect and see the passhash error message, the reason may be missing keys for the Diffie–Hellman key exchange (D–H). Please update PRTG to this version or higher. We have already released a PRTG update with version 16./3270 that makes it possible to login with PRTG for Android on Android N. The error message of PRTG for Android which may reflect this issue is “could not retrieve passhash”. These changes also affect the secure connections between PRTG for Android and your PRTG server and may result in unsuccessful login attempts on Android N devices. This article applies to PRTG Network Monitor 16 or later and PRTG for Android 16 or later Failed Logins to PRTG for Android on Android NĪndroid N includes several changes to its SSL library compared to previous Android versions.
