Created attachment 123736 [details] KDE Screenshot SUMMARY When I click on external links in applications like VSCode, a pop-up appears with "ERROR: KIO client <4>/ The file or folder http://localhost:8000/ does not exist" STEPS TO REPRODUCE 1. echo http://localhost:8000/ in the KDE console 2. Hold CTRL and click on the link 3. The same message is produced, only without "error: kio client <number> OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
In KDE "Default Applications > Web Browser > Open http and https URLs" is set to "in an application based on the contents of the URL" when setting it to "google chrome" or other, the links are opened as expected
This confusing feature has been removed in Plasma 5.19, which should fix the issue.
