Rb 493AH is disconnecting and connecting the ethers doors

Hello,

Pop is my scenario:
RB493AH version 29.6 source with direct 24v 3a UPS
1 Nano Bridge 25 with ubiquit source also in UPS
Source Volt 24v 7a
Regua Poe Volt gigabit
3 Rocket version 5.6.3
1 Nano Bridge 25
RB 493AH power that Rb is a source energetically tested 24v and the link with Nano Bridge 25 with source ubiquit both of them bound in UPS and the remaining bound in the ethers that Rb, powered by ruler puts Volt, the problem is that it has few months that these panels are disconnecting and connecting alone, already changed everything from Rb (other 493AH), Rocket, to the source and poe rule that feeds these panels, only the panels disconnect and reconnect the link is what is in Nano Bridge the source does not happen that someone has gone through this problem and had solution, or have an idea how to solve.
Thank you,

William Edy
