Hello Joanna,
Community 3.1.0 uses AWS with CloudFront Content Delivery Network to ensure high download speeds all over the world. This requires reaching a dynamic set of IP addresses.
To resolve firewall issues in 3.1.0, we recommend whitelisting inbound/outbound TCP protocol traffic in port 443 for Community executable files.
Default paths for these files in system-wide installed Community are:
Main Community 3.1.0 Application file
C:\Program Files (x86)\Pinnacle 21 Community\Pinnacle 21 Community.exe
Java executable file (for 64-bit systems)
C:\Program Files (x86)\Pinnacle 21 Community\resources\app.asar.unpacked\components\java64\bin\java.exe
Java executable file (for 32-bit systems)
C:\Program Files (x86)\Pinnacle 21 Community\resources\app.asar.unpacked\components\java32\bin\java.exe
Default paths for per-user installation are all similar, but instead of “Program Files” they are inside
*C:\Users%USERPROFILE%\AppData\Local\Programs\Pinnacle 21 Community*
Thanks,
Philipp
