Sonarr doesn't update to new version

Help & Support
1

i’m using the mac version, but the in-built client updater doesn’t seem to work.
i see the prompt saying new version available.
i click "install update"
it’ downloads, verifies, and unpacks.
it says it will restart, it does.
once restarted i am still on the same version and the update is still showing as available.

when checking the logs i see

Starting update client /var/folders/j1/ddm_lc6j45v13l38hch21mtm0000gn/T/nzbdrone_update/NzbDrone.Update.exe

however, and EXE file is for windows, not mac.
is it downloading the correct update?

update - it only seems to fail if i access sonarr remotely.
if i attempt to run the update from inside my network then it completes successfully.
