When I try to access my PRTG server from my iPhone/iPad using the official iPRTG app, I get error messages, e.g.

"Error Loading Data The Server Version (8.4.2381) of your PRTG-Installation is too old. Version 12.0.0.0 or later is required to run iPRTG."" or
"The username/password credentials of your authentication can not be accepted."

Why Does iPRTG require Specific PRTG Versions?

Different versions of iPRTG for iPhone and iPad in the AppStore (free download) require different versions of the PRTG server, because they use different API calls and/or data formats.

Each version of the iPRTG app checks the version of the PRTG server before it logs in and accesses data.

What Server Version Do I Need?

Our goal is to support all server versions of the previous 6-12 months, if possible.

iPRTG version	Release Date	required PRTG server version	Date of required server version
iPRTG 2.0	August 2009	PRTG 7.0 or later	July 2009
iPRTG 3.2	August 2011	PRTG 7.3 or later	July 2010
iPRTG 3.3	May 2013	PRTG 12.x or later	May 2012

Can I Get an Older Version of iPRTG?

No, you can't. Due to limitations of the AppStore we can not offer more than one version of iPRTG at any one time. Also we can't simply send you an older version via email, as under iOS apps must be installed from the AppStore.

You need to upgrade your PRTG server to the required version. You can do so by using the Auto-Update feature (in the "Setup" menu of V12 or later) or you can download the latest installer from https://www.paessler.com/login.

Note: You must have an active maintenance contract to get the latest version.

Can I Downgrade My iPRTG to the Previous Version?

This is not officially supported by Apple's iOS ecosystem, but the pages linked below describe a way how to do it.

Requirements:

You must have synced/backed up your iOS device with your iTunes installation while the previous version of iPRTG was installed (iTunes copies the binaries of apps onto the local disk)
You must have a backup of those old files

Note: If you backup exclusively through iCloud you won’t have this option because the apps will not be stored locally. You can always backup locally in addition to iCloud to prevent that being an issue.

We cannot offer support for this process, but the following links should help you (we have not tested these ourselves, though):
