SSL_ERROR_NO_CYPHER_OVERLAP (Firefox) OR ERR_SSL_VERSION_OR_CIPHER_MISMATCH (Chrome)
Hello. For some days (I would say after updating Firefox and Chorme to the latest version) I can not access the web version of the nas interface, updated to the latest firmware available on 5.3.13 .....
I'm having exactly the same problem on Firefox and Chrome.
On Chrome, the full message is:
This site can’t provide a secure connection
192.168.1.236 uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Enviroment:
Firmware 6.9.4
Windows 10
Firefox v63
Chrome v71
The Duo V2 is already a legacy NAS so this has something to do with an outdated https implementation and certificate. There are no more further updates for this NAS so it is not fixable. The only suggestion that we can provide is to try a different web browser.
You should not have experience the issue since you already are on the latest firmware. The problem that you are describing with IP vs DNS, working with DNS but not IP, means that either the SSL cert needs to be regenerated from the HTTPS tab or there is another issue You may also enable Secure Diagnostic Mode so we can check this issue further. You may PM me the 5-digit number after enabling it.
Same as what I have told Caesium, you should not experience this error with the latest firmware 6.9.4 hotfix 1. Please enable also SDM on your NAS then PM me the 5-digit number so we can further check this.

Hello everyone.
Today I found a browser named Lunascape6 and finally I managed to get the web access of the old Nas Duo V2. I hope it can help.
Thank you - this works perfectly for me!
Hi JohnCM_S
I've managed to get into the admin screen using the Lunascape browser. I can PM my 5 digit number to you.
Hi Roel1, if Lunascript works, your issue is most probably caused by the browser engines in firefox (gecko) and chrome (blink forked from apple's webkit). Lunascript however can use three different browser engines depending on situation. Beyond gecko and blink the third one is trident from ancient Internet explorer. I hate too much speculation, but would not be surprised, that your Lunascript is using trident to render the admin page of the nas fossil. I would like to support StephenB's suggestion to switch to OS6 to get rid of the problems.
Some more background about Lunascript and how to control the browser engine being used by it here
