SSH Access - Upload SSH public-key - Access denied

[imbaSD]

Yesterday i was trying to setup a SSH Access via Key that i generate with Puttygen. So i make a key and save the public key file and private.
When i try to upload the public file through GUI - Router Access i experience problem and couldnt access the router.

What i did

Generate the keys with PuTTYgen v0.73 - RSA 2048 and save them at PC

Go to Router Access and at Upload SSH public-key: i chose the public key (no matter what name i put public/public.pub/my/gargoyle.pub/gargoyle) and at SSH Key Name: i put different names (my/gargoyle/etc...)

Disable password access before you enable remote SSH access

At WinSCP or PuTTy i set up the location of private key (.ppk)

and when i try to connect i get error that my key wasnt accepted. Even i try with different ports but the result same (btw i was connected wirelessly to my router)

After a lot of hours of Trying i found that the keys are stored at /etc/dropbear/authorized_keys and when i open the file i saw only the SSH Key Name: that i put (my/gargoyle/etc...) nothing else, so i delete everything and paste manually the key-string from puttygen and save it. Then i Disable password access before you enable remote SSH access, enable the SSH and vioala i was connected


Was i doing something wrong via GUI?

Firstly, don't disable password access until you're sure that keyed access is working.

There may be some error in the browser.
When you upload the key file, what do you see in the table?
You should see a preview of the key and the name that you entered.

If you can check the browser console for errors, this may help diagnose it.

Just made a test file and upload

I am using Chrome, could you tell me how to perform this?

There's nothing obviously wrong there.

Press F12 in the browser, and watch the console for errors when you hit "save changes".
Again, i'd advise that you don't disable password access while you're experiencing this issue.

hope did it correct, as you can see with new test key access denied but with other key (witch i enter manually as i mention in the beginning) all are ok

Nothing out of the ordinary there.
Can you please delete both keys, then load the failed one again via the GUI, and provide a "logread" around 60 seconds after pressing save changes?

Sorry for delay of replay
Here we are, seems same. Was more than 60 sec

Is there a logread with it? I don't see one.

That's not the full log.

I'm not able to solve this for you sorry.
Unless someone else can demonstrate they also get the error, and can show me a way to reproduce it 100% of the time, it's just not possible for me to guess a fix.
