Yeah, this 
While reviewing comics, I very occasionally come across one where it genuinely, truly is a really high quality comic that's just at the wrong time, or on the wrong platform to be popular (search "Bloodshot" or "Rest Area 51" for good examples of this on Tapas).
....The vast majority of comics under-performing on Tapas though... including a lot who say "Oh, my work is really good and clearly just not popular because it's [page format/black and white/ non-manga art style / not romance-focused/ heterosexual]!" It's actually...er.... lacking in the art or writing department as a much more prevalent issue. Weak composition, sloppy line work, unfocused plot, unlikeable characters, poor font choices or font size too small for the platform, bad use of space, confusing visual storytelling, bad use of value and colour to make things readable, speech bubbles shaped like rugby balls, busy covers etc. etc.
Fix all the issues with your comic first. Get feedback from professionals. You can blame the fact that your comic isn't BL for your lack of success when you've definitely established that it 100% isn't actually that you still need to do some work.on yourself before you blame other people for your lack of success.
