TrueNas Scale 25.04.2.6 - Gmail keep dropping out

My gmail keep dropping out on truenas scale 25.04.2.6.
I am using gmail’s Oath and forced to repeatedly connect to my gmail account to give access.

Anyone know why this is happening? Its annoying since alerts cant be sent when it drops out.
No issues connecting and giving nas access to the email account, but then at some point it cant connect.
I haven’t noticed a particular pattern to this other than noting email failure alerts when logging on the the server. … and each time I see these email failure alerts Im forced to re-initiate the access to my gmail account and save the setting.
What more can I do the ensure truenas can keep the email alive/active? Is it google or is it something within the truenas scale fangtooth 25.04.2.6?
