I've got a Pegasus(1) R6 connected with a Thunderbolt3->Thunderbolt2 adapter to a brand new Mac Mini.
Since I upgraded to 10.15.4 (or around that time frame?) the Promise Utility stopped working, and reports:
Cannot launch Promise Utility (apache server), please change the port with user menu.
Changing the port doesn't help.
I've tried uninstalling and reinstalling both R_Promise_Utility_400000009.dmg and R_Promise_Utility_402000021_1013_1014.dmg and R_MacDrv_V6.2.9.zip to no avail.
Any idea what I'm doing wrong, or how I can fix this? The drive is mounted and works fine, but I had a drive fail and get replaced, but I need to tell the array to rebuild, and I can't get into the UI...
Thanks!
