When trying to use the automatic software update of PRTG, the "latest auto-update message" shows
Update download in progress... 102 of 103 MB
for several minutes, then it shows
Autoupdate: Error while downloading update (Read timed out.)
What can I do?

Check your Anti Virus / Anti Malware Product
Most likely, there is an anti-virus or anti-malware product running on the computer where your PRTG core server is installed, and this product blocks the download performed by PRTG.
For example, we've seen such a behavior on systems running ESET NOD32 Antivirus.
So solve this issue, we recommend you either disable your protection product temporarily during download and installation, or you add the PRTG program directory to the excluded paths, so PRTG's files are ignored permanently. You might also need to explicitly whitelist the paessler.com domain.
The exact settings on your systems will vary depending on the security product(s) you use.
Example: ESET NOD32
In our case using ESET NOD32, it was necessary to enter the advanced configuration mode and add the string *paessler.com* to the "HTTP address management" exclude list of the Web access protection component, in order to successfully use PRTG's auto-update function.
