Cannot connect using Edge, Keepassxc opens when clicking the browser reload button (reload button on the keepass addon I mean)

[TxTechnician]

Expected Behavior

Current Behavior

I cannot connect to keepassxc from microsoft-edge-stable. When I click on the reload button in the extension. Keepassxc, if it is already open, opens. But there is no prompt or anything. It just opens to the screen I last selected in Keepassxc.

Error message shown in browser extenstion:
Cannot connect to KeePassXC. Check that browser integration is enabled in KeePassXC settings.

It's a known problem that sometimes the Flatpak tries to start KeePassXC instance instead of keepassxc-proxy. I can try and search the relevant tickets later that could help solving the issue.

[TxTechnician]

That would be helpful. Any workaround I can find for the flatpak version. Because I would like to continue to use that version.

Do you know if the problem happens with the snap version?

[varjolintu]

Creating a shell script (part 2-A here) has worked sometimes. I must refresh my memory how the actual issue was solved, or is it already solved by modifying relevant scripts inside KeePassXC.

Snap is not recommended.

"Snap is not recommended."

Seems to be a common phrase shared by many linux users.

I think we have a regression need to look into the flatpak distribution
