A lot of what I wanted to say has already been said: It's about how the trope/genre is used. Of course, there's a lot of bad stuff, 90% of all stuff is bad. It's successful and easy so people copy and quality drops. Bad writers will often fall into the pitfalls of the genre/trope. It's because the community and therefore audience are those that seek wish fulfillment and escapism. You got to bring something new and unique. You got to grab interest. It's not bad to follow cliches/tropes. You just got to comb through, seek the good ones out, or just accept it. Just keep going with it as you'll find an audience eventually. Yadda, Yadda.
The thing I want to add to this discussion though is Expectation Management and Character Audience Distancing.
It's something I feel every author especially ones that want to post their story online on these kinds of sites (SH, RR, SB, etc.) should learn and know about.
I haven't read your story so it might really just be a case of readers not liking something because it wasn't to their taste and because they didn't care to really see it for what it was. Still, I want to talk about Expectation Management and Character Audience Distancing because it's something I don't hear much about it and because I would like to share it with other people.
When you read traditional, fictional literature like the non-escapism kind you'd read for school, you understand that the main character is just a character. He/She/They/It is separate from the author AND you, the reader. Furthermore, you know the author isn't trying to satisfy you and always make you, the reader, happy. They're trying to express creative ideas, convey some theme or social commentary, or share some sort of emotion, life experience, etc.
With web novels especially the escapism kind that this and many related sites are saturated with, (some) readers don't have that understanding and separation. Because they read for that enjoyment, that specially catered to them story. That's why they browse such sites.
If an author is going to write a story that goes against what the usual audience expects and wants, they need to really really make it clear what the story is about. After all, it's not on you if you tagged your story as harem BL smut and the reader still clicks/ignore those tags and then proceeds to complains that it's harem BL smut. It said so right on "the box."
It's kinda like with movie trailers. If the movie is completely different from the trailers, people will be upset. The problem is that with web novels, the movie trailer for most readers is the other novels on the site and the entire community itself. You need to make sure the thing on their mind is your "trailer" because that's the thing you control. You need to control what expectations they have.
One way to control it is by snapping your readers out of that escapism seeking mindset even if only temporarily because then they'll view it like an actual story rather than a tailored experience/drug.
One way is to establish that the main character is their own person. You have to bash it into the reader's skulls that the MC is not there to act as their surrogate/placeholder. You have to distance the MC from the audience. This can definitely be challenging if you want the reader to relate or see themselves in the MC.
If you want to tell a survival story with a normal/everyday modern person as the MC, you're really going to have to show the level of normal the MC is. Everyone knows a normal modern-day human is weak and can do jack shit in a fantasy death world. However, some of your readers, the escapism filled ones, are gonna use themselves as the point of reference for normal. Or more specifically, the more capable version of themselves in their heads mixed with all the other "normal guy" MCs they've read.
You should, in the beginning, really show how out of their element the MC really is. Show a big monster destroy miles of trees and the MC hiding in a hole. If your MC is going to be weak for most of the story, really double down and show that through the MC's thoughts or the MC acknowledging that they are weak. If the MC is an otaku and familiar with Isekai, maybe bring up that they aren't some Isekai protagonist that knows how to build a steam engine or how in real life, just being a "nice guy" isn't gonna get you chicks.
To manage their expectations and snap away their tunnel vision stand-in MC escapism seeking mindset, you could try to really show the individualness of the MC or really double down on the normality of them. Start off the MC's introduction by bringing a bit of reality into it.
For example, have your MC think about a very specific instance in their childhood. The MC remembers his fifth-grade classmate, Timone, and how for some reason Tim brought a bag of flour to class, and somehow the bag got dropped, exploded, and got everyone completely covered in flour for the rest of the day. It's a "childhood memory." It's something extremely normal. Everyone has them, but I doubt everyone would have a Timone flour bomb memory. You could also have the MC talk about his 2nd place medal in a yoyo competition. It's like when an MC references a series/genre you don't watch and starts to go in-depth about it. You don't understand or relate so you start to separate yourself from the MC. Maybe have them mention their family, by name too, because most Isekai MCs don't do that.
Stories are just lies that people chose to listen to and sometimes believe in, even if only temporarily. An author needs to be a good liar and know how to manipulate his/her readers.
