I have 4xPA2 ultra and suddenly all of them at once no longer seem to communicate with the Aquaero after months of use and no issues. I get no rpm signals from my fans and the PA2s report 12V output even though the fans are spinning at about 35% of maximum. The fans no longer respond to the controller I have set in Aquasuite and have disappeared. Also 2xD5 (Aquacomputer mps version) also no longer communicating with Aquaero and disappeared from Aquasuite. Aquabus seems to be not functioning?

Haven't tried anything yet to determine fault/solution.

Anyone with any ideas what may be going on? Software or hardware issue?

Thanks in advance.

Never mind. Found the problem.
