problem with Mikrotik CCR1009-8G-1S-1S +

Hello, the problem with Mikrotik CCR1009-8G-1S-1S + (6.41.3). Repeated 1 time in 2-3 months. Running Winbox presses connect, an error appears that is not a valid password, I just go in without a password and it starts up, I can not save backup, an error (6), all that I fix on it is not saved. Sometimes, in this case, DUDE writes that it does not activate, or the database is up to it.
I reboot Mikrotik and everything is fine again (it saves everything, my password remembers, DUDE works, etc.) until the next such case.
This is no longer treated?

Are you using latest winbox (3.15)?

It can upgrade itself, check Tools > Check For Updates in Main Winbox window.

If you suspect the CCR is misbehaving, I’d take a full export out of that CCR, netinstall it, then import the export file back watching out for errors.

If there are any, you can proceed by copying and pasting the .rsc file contents by blocks on a terminal, watching out for any failed commands fixing them as required.

Unless current is required, I’d go with bug fix version, 6.40.8 as the time of writing.
