Hello Normis.
On one of my rb433’s I had an l2tp connection that unexpectedly reconnected every 30 minutes. This did not happen after downgrading back to 4.10. The connection has been up for 12 hours now.
I did remove the old userman backup and reconfigured it this morning.
Everything it back up and running.
Thank you.
PS: Here is my post about the l2tp problem i had.(hopyfully solved now)
