Charlton could not find a way past struggling Fleetwood in a drab affair in front of their lowest Saturday crowd of the season.
The Addicks played out their bore draw with 9,865 fans watching on.
Charlton were very poor - and missed an opportunity to close the five-point gap to the top six.
Karl Robinson made three changes to the side that lost to Blackpool on Tuesday evening with Naby Sarr, Joe Aribo and Mark Marshall coming in for Chris Solly, Lewis Page and Michal Zyro.
Ben Reeves went close on 15 minutes when he dragged a shot wide from close-range after winning possession back before Tariqe Fosu worked his way into the box only to see his goal-bound effort blocked.
That was it in terms of meaningful chances in the first-half with both sides clearly lacking in confidence.
The Addicks were deservedly booed off at the end of both halves.
Fosu, the only Charlton player who was trying to make something happen, saw his cross come shot tipped away from danger by Alex Cairns after the restart.
The Addicks still struggled to create openings and Robinson responded by bringing on Nicky Ajose and Zyro on the hour mark and switching to a 4-4-2 formation. Fans were crying out for a change in shape earlier on.
Just a minute after the double substitution, Ben Amos came to Charlton’s rescue with a fine save to deny Ashley Hunter as Wes Burns put the rebound wide.
Charlton had half chances as the clocked ticked down but Fleetwood looked more likely to score.
The visitors broke away as Burns found former Charlton loanee Conor McAleny whose strike trickled wide thanks to a vital block from Jason Pearce.
The relegation-threatened side went close again late on when Jack Sowerby’s deflected shot fortunately found Amos’ palms.
Charlton XI: Amos, Konsa, Bauer, Pearce, Sarr, Forster-Caskey, Aribo, Marshall (Kaikai 66), Reeves (Ajose 60), Fosu, Magennis (Zyro 60).
Subs not used: Maynard-Brewer, Lennon, Dijksteel, Jackson.
