There are several valid ways to go from here depending on your goals and progress on the current story:
You can press onward
If your main goal is to tell this particular story (rather than like gaining as many subs as possible, or etc.) then go for it! OOOOOR if your story is anywhere near completion (like maybe 2/3 or more done, or like 30-50 pages or less) then I would also recommend thinking about finishing. Having completed work under your belt is a big deal as a creator, even if it wasn't exploding in popularity. A lot of lessons can be learned that way for your future work by working through the full beginning, middle, & end of a story.
You can revise to shorten it down and then finish that
If your story is a ways from completion (like way more than 30-50 pages or like less than half complete) and you're feeling unsure about whether to see it all the way through or not, you could consider taking a break to review your outline and script and see if you can edit it in any way to reach a satisfying conclusion in a reasonable amount of pages, then move forward and complete those. That way you don't spend like years committed to a story that's not doing as well as you'd like, but you still get the above benefits of reaching an ending (as well as added benefits in editing a script down xD) and the readers you do have might be happy to reach some sort of conclusion as well~
Drop it and try something else
Although it might not be the most satisfying solution for either you or your readers, there is something to be said about the time efficiency of cutting your losses and trying something new with hopefully better results. If you're nowhere near an ending point and it would be impossible to create a good early one without it taking way too long for you, then this is a viable option as well. If you're doing this as a hobby/or hoping to break into the profession but not there yet, there's nothing stopping you from jumping ship to a new project.
I clicked your comic link after writing this post and see that you're only 4 eps in... at this point you might just need to just give it more time. Keep in mind that comics are a long game and it's not typical to explode overnight. If you decide to stay with this comic though I do advise you evaluate how long it is and think about ways to possibly cut it short in a satisfying way down the road if it continues to fail meeting your expectations for performance.
