Constantly requires pairing (after changing cores) More Info

I change my core location frequently. All my extensions constantly ask for pairing. Pressing pair for the extension manager works for a few hours/minutes. Pressing pairing for ropieee rarely engages and if it does only for a few hours. Can anyone help me correct this? Thanks.

Returned roon core to the machine on which the extensions were originally installed. The pairing here is holding.
