Workaround for ERR_SSL_VERSION_OR_CIPHER_MISMATCH problem for Sparc NAS (4.1.x firmware)

Thanks for this workaround - but could I ask how to do you actually make these changes step by step? I don't know how to access this to make the changes in BLUE that you've highlighted.

Here's one way.  As usual, you are at your own risk when using SSH to make mods to the NAS.  But if you have problems you can of course post here (I suggest using opening a different thread).

(1) First you need to regain access to Frontview, so you need to begin with either using Internet Explorer, IE mode in Edge, or a old version of a browser (for instance FireFox 94.0.2).

Note that if you are running 4.2.x or 5.3.x firmware, then you can install the add-on from www.rnxtras.com at this point.  That installs TLS 1.2 on those NAS, which is enough to give you access.   So you can stop at this point.

(2) For the 4.1.x systems,  you need to enable ssh access, using the Netgear Enable Root SSH Access add-on found here: https://kb.netgear.com/24546/Add-ons-for-RAIDiator-4-1-3-Sparc.

Then install notepad++ on the PC from https://notepad-plus-plus.org/downloads/.

(3) Copy/Paste the file from the post above into Notepad++. 

Go into Edit->EOL Conversion of Notepad++, and choose "unix".  It will gray out that option when you do that (a somewhat non-intuitive way of marking the selection).  This is a very important step, so make sure you get this right.

Then save the file as Virtual.conf directly to a share on the NAS.  Let's call that share "sharename", and assume it is on the C volume for now.

(4) Now access the NAS using SSH.  Use root for the username, and the NAS admin password.  If you are using windows 10, then you can do this by entering 

ssh root@nas-ip-addess

from the windows search bar (using the real NAS ip address of course). Windows will ask if you want to proceed (something also about saving the fingerprint). 

I'm not a Mac owner, but I believe you can also enter this same command into terminal.

Either way, you'll get a prompt for the password after you enter this command - as I said earlier use the NAS admin password.

(5) Once in, you need to copy Virtual.Conf to the destination folder.  The steps below save the original file, and keep a separate copy of the changed file in the destination folder.  The last command makes sure the owner/group is preserved.

cd /etc/frontview/apache
cp /c/sharename/Virtual.conf Virtual.conf.mod
mv Virtual.conf Virtual.conf.orig
cp Virtual.conf.mod Virtual.conf
chown admin:admin Virtual.conf*

using the real sharename you stored the file to in step 3.  Of course substitute the real volume if you are using flexraid (and didn't put it o the c volume).

Reboot the NAS, and it should connect to Frontview with current browsers when you enter http://nas-ip-address/admin

You can alternatively just restart Frontview:

/etc/init.d/frontview restart

Note if this fails to connect (even with IE or the older firefox), you can still get into the NAS with ssh, and troubleshoot from there.
