RT-AС86U OpenVPN Trouble

Hello!
I am facing the following problem:
I have a router RT-AC86U firmware version: 386.7_0
For the second time in 3 weeks, OpenVPN profiles are erased on my own, and so are all routes.
I do not understand what it is connected with, here is what I found in the logs:

Code:

Sep  1 07:35:34 Samba_Server: smb daemon is stopped

Can someone help me figure out what's going on?
Thank you.

Unfortunately that section of the log doesn't tell us anything other than you don't have valid CA files for your VPN profiles.

The certificates are stored in JFFS so if that's full or unmounted it will be a problem. But you'd likely be experiencing other problems as well because of that.

If you upload the complete System Log to pastebin.com and post a link to it we might be able to spot something.

There are CA files, but VPN worked for me all this time.

unfortunately there are no more System logs left, I had to fix the problem by resetting the router to factory settings and setting up the configuration from the very beginning.

But if I have this problem again, I will take all the logs and send you here.

Here is this line, it is not clear why he cleaned all the routes on his own, what made him do it.

That's a normal message. The VPN client is shutting down so it removes the routes that it created.
