My ReadyNAS NV+ RND4425 has been working great for many years. I just purchased a new PC (HP Envy Desktop, Intel Core i7-10700 8-Core Processor, Intel UHD Graphics 630, 64GB DDR4 RAM, 1TB SSD + 2TB HDD, HDMI, VGA, USB Type-C, Wireless-AX Wi-Fi 6, Bluetooth, Windows 11 Home). I cannot access the NAS when connecting to me new PC. I turned on SMB and that didn't help. When I click on the NAS drive icon that shows up in the Network section of This PC, I receive the following message: Error 0x80004002: No such interface supported. When I try to go to the NAS Radar site, I receive the following: This site can't support a secure connection. 10.0.0.22 uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Not sure what firmware I am running as I cannot access my NAS as this time, but it has been a very long time since I updated the firmware. I appreciate any ideas / assistance!

You can try running Edge in IE mode - there is a useful guide for that here: https://www.pcworld.com/article/632674/how-to-use-internet-explorer-mode-in-microsoft-edge.html Then browse to https://10.0.0.22/admin If that fails, you can alternatively install an old version of FireFox (94.0.2 works), and connect with that. You will need to manually disable autoupdate in the browser. Either way, you will still get a security warning that you will need to click through (but not the SSL Version/Cipher Mismatch error).

Thanks Stephen. I was able to get to my share lists via file explorer as you recommended. I am still unable too access the Radar admin web page even using the IE mode workaround you explained, although the message is different now. I am getting an authentication error. Assuming it requires my id and password, I am not sure how I go about entering my id=admin, password=netgear1 credentials as I am not given any screen to enter. Is that something I need to do via CMD, which I have no idea how to do? What do you suggest as my next step? I really appreciate your help! David

Assuming it requires my id and password, I am not sure how I go about entering my id=admin, password=netgear1 credentials as I am not given any screen to enter. There are a couple of possibilities here. One is that the browser might have the old password saved. You can try opening an inPrivate window in Edge - if that's the problem, then it should get you to the pop-up window where you enter the credentials. Maybe also make sure pop-ups are allowed ( go to edge://settings/content/popups ) You will also still get a security warning from the browser, because the NAS certificate is self-signed. You can overcome that by clicking on "advanced", and then clicking on the link that the browser thinks is "unsafe". Note your error message might not be exactly the same as the one above.

Hi Stephen. I followed all of your recommendations and after clicking through advanced for the unsafe content, I am receiving the following:Authorization RequiredThis server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required. Any other ideas or suggestions on how to get to Radar? I can now access my NAS shares from my PC so that is a huge step forward, thank you. Please advise at your convenience. Appreciate your assistance!

If not, is it possible that the browser has saved old credentials for the NAS IP address?
