Unable to Connect to PortableApps.com After Windows Update

Hi everyone,

This is is my first post here. I'm having trouble connecting to PortableApps.com to retrieve updates for my portable apps. This issue started after a recent Windows 11 Enterprise update. I'm behind a corporate firewall.

When I try to check for updates, I get the error message: "Unable to connect to PortableApps.com to retrieve portable apps. Please try again later. [ ÌnvalidZipFilePossibleNoConnectionOrFirewall ]"

Also, although the platform starts, most apps won't run, some show a splash screen but don't start. The only app that still works is PDF X-Change Viewer.

I've tried to take the following troubleshooting steps, but couldn't because they require administrator access:

Couldn't check whether PortableApps.com is whitelisted in my firewall.
Couldn't check Internet Explorer as it's no longer available.
Updated PortableApps platform: I'm using the latest version, I checked on a different PC.

The issue persists. Does anyone else have similar experiences or suggestions for resolving this problem?

Thanks for your help!
