Yes, if you hear the signals your radio is receiving them, but it appears unable to decode them. If you’re not seeing anything in the decoded messages, check your computer clock. It has to be set precisely. You’ll want to link it to an internet time source.
Also, what does the waterfall in the secondary screen of WSJT-X look like? If it’s busy you should see it light up all the way across. If not, check your filter width. I make sure I have no filters on when receiving FT8.
Then, what does it look like in the list of heard stations on the left side pane in WSJT-X? You should see a relatively steady scrolling list of messages.
Depending on how you have your colors set up you should see CQ calls in the left pane. Double clicking on a CQ should result in your station responding to that particular CQ.
Finally, how is your transmit power set up? I set my output power on the radio fairly high, but then I use the Power slider on the right hand side of WSJT-X to limit my output power to something like 45 watts.
