you cannot access your reclaim if it is on a locked world, you mentioned that the portal showed locked, does it say the planet is locked but the portal is still active?
then you have 2 options
- manually reclaim the beacon that has your active reclaim open, it will just go into reclaim again
- or fuel the planet to access it
if so you can remotely reclaim your beacon on a locked planet see below
if you did not get the fuel code (also check the spam folder) then send a support mail to support@playboundless.com, and I’m sure they will be able to help you out.
