WebSocket connection failure. - Unable to establish remote connection

hi all sorry total newbie - very frustrated. 2nd time I try to start with neo4j (some months ago already failed :( -

I´m not a coder - nothing. Just super interested to get it running.

I got it installed but it doesnt even connect so thats it already so far.

I dont understand whats going on. 1st time I have to do with sql syntax/no sql. really total starter.

just downloaded latest version (cant even see it cause doesnt connect). browser is
Opera One(Version: 100.0.4815.76)
win 11 on surface go 3

heres the error message

"Unable to establish remote connection: Neo4jError: WebSocket connection failure. Due to security constraints in your web browser, the reason for the failure is not available to this Neo4j Driver. Please use your browsers development console to determine the root cause of the failure. Common reasons include the database being unavailable, using the wrong connection URL or temporary network problems. If you have enabled encryption, ensure your browser is configured to trust the certificate Neo4j is configured to use. WebSocket readyState is: 3
The following logs may help you diagnose the issue:"

dont even know what a websocket is.

I disabled adblocker now. no clue even where opera dev console is or how to use it :((

And that really sucks!: I cant post the logfile because as a new user I can only share 2 links but there are 15 or so . Can´t believe it !

can´t even upload a screenshot! I mean .. how can I help myself with such an infrastructure? I also didnt find anything in this forum.

:((

I really wonder if this is possible for "normal users" without coding and extensive software understanding (see websocket bla.. )

I use PCs since 30 years! Not that I recently started.

thanks
really grateful if someone helps me through.
or should I better leave it!??

the troubleshooting helps zero

i think this is a joke for beginners. I think they should be more clear with the prerequisites. :frowning:
Lost already a lot of time with it hoping i get it running :(

it is extremely frustrating
there is no clear step by step explanation how to start and get there . even if they would say hey, you got no chance if you don´t know A, B, C .. learn that first and then learn neo. maybe they are even not aware anymore about normal peoples understanding and necessities. Very bad experience.
isa

I installed everything a new and got it running.
