It's the original Duo - called the v1 here. The v2 in the part number indicates a minor hardware revision. The Duo v2 (which runs 5.3.x firmware) is a very different platform.

It looks like it has something to do with an outdated SSL/TSL certificate.
No, not the certificate. The legacy NAS use TLS 1.0 for https connections. That's outdated, and browsers have recently dropped it - requiring at least TLS 1.2. That is why you get the SSL version mismatch error.
There is a workround for the Duo posted here: https://community.netgear.com/t5/New-ReadyNAS-Users-General/Workaround-for-ERR-SSL-VERSION-OR-CIPHER-MISMATCH-problem-for/m-p/2198243#M47827 There are some more details on how to make the mod in post 5 of that thread.

Also my backup processes stopped working. I get a mail confirming that the Backup Process has run, but no backup has taken place.
That sounds like a different problem, but maybe circle back to it when you regain access to frontview.
Thank you for the information- both about my version confusion and for clarification of the TLS mismatch Error. Just after I postet my question I discovered that I can accessFrontview from the browser in my Ipad (running IpadOS 15.3.1).
Based on your response I spent som time (no, a lot of time) investigating the posibilities and finally I chose to access Frontview through Firefox on my PC.I still have problems with my backup - even though my backup settings worked fine before i had the TLS mismatch error.
@StephenB
Now I have been working on the referred workaround. I get stuck in step 3:
"Go into settings->EOL Conversion of Notepad++, and choose "unix". "
It seems that my version of Notepad++ doesn't offer this option (see picture)
I have been trough all the shown options. It is probably due to lack of expertice, so maybe you can help me on thisone as well.
It's my mistake - the setting you want is actually under "edit".
