Because you didn't explain what it was, you just said "turn it off if you're not using it". The link just says that the entries appear after the update, so I deleted them.
The only question is how to remove the certificate selected for openvpn from the configuration.
But is not… “turn it off if you’re not using it”???
On post #2 is explaned, other users can judge if is true or not that I at least explain why happen that.
You do not ask any info about what are those instructions and and what are they for.
And regarding ovpn-server certificates, if I had already put that line at the beginning, I would have had the answer.
But I see that you are not even good at googling what you already found before, it already has the answer for the ovpn-server…
From your link…
If you reset this item to its new default so:
/interface ovpn-server server
set auth=sha1,md5,sha256,sha512
As far as I understand, Certificate field cannot be left blank. If I did through the console, then the problem would not appear. But I already did it through winbox and now the certificate is selected.
So my question is how to reset a field that cannot be blank?
The question itself accepts no answers.
How to delete something that shouldn’t be deleted???
The value is “string” (id as string, for be precise) and can not be “nil”/“nothing”,empty, but at least one id.
No matter if exist or not one certificate with that id.
Using winbox you configure all the parameters at same time, and certificate is needed by ospf for work.
Is why winbox do not accept unexistant certificate and you must specify one.
"unknown" because winbox do not find the cert with id "*0"
If you add any cert to the device, if never set differently, here appear the first cert you add to the device.
If you "print" on terminal, you can see the cert id *0 (that probably on your device not exist)
