'Can't start httpd - Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/*/Library/LaunchAgents/homebrew.mxcl.httpd.plist` exited with 5

Just tried accessing my localhost today, but it doesn't work. I worked yesterday, but I believe it's because my Mac crashed. I've tried started httpd again with brew services start httpd. This results in:

Bootstrap failed: 5: Input/output error Try re-running the command as root for richer errors. Error: Failure while executing; /bin/launchctl bootstrap gui/501 /Users/UserName/Library/LaunchAgents/homebrew.mxcl.httpd.plist exited with 5.

Have tried reinstalling httpd, but it still gives the same error. Any ideas what the cause can be?

I had the same problem after I upgraded to macOS Monterey. But I solved my issue via these commands.

Unload homebrew.mxcl.httpd.plist

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.httpd.plist

And then load it again:

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.httpd.plist

After that I used this command to start httpd again.

brew services start httpd

Just thought I'd share what worked for me for anyone else still stuck...

It seemed I had a version of apache running which was stopping the brew version. (thought I'd removed the built in apache already!).

This also happened after my Mac crashed and got the exact same error message but I did:

Stop brew httpd service completely

brew services stop httpd   

Stop Mac Apache leftovers

sudo apachectl -k stop

Start brew httpd again

brew services start httpd

Started like a charm and solved my issue.

So after trying a lot of things, this seemed to work:

Trying what Volex suggests here (brew services. Cant start service. get "Bootstrap failed: 5: Input/output error") gave me a more precise error message.

The new error message led me to this: apache doesn't work after upgrade of macOs Sierra brew reinstall apr-util fixed the problem.

After trying ALL the solutions proposed all over the place, what finally did it for me was changing the owner of the log files in /usr/local/var/log/httpd to my user, instead of root.

sudo chown [username] *

This took me hours to figure out, sadly - I even removed and reinstalled httpd (which was actually a good thing, because there was a n older version's keg knocking around back there).

In some cases will help restart HTTPD.

brew services restart httpd

It happens to me when the PC crashes for some reason and httpd is running, but localhost is "down". Or you can stop httpd and restart PC. Then start httpd and it's ok.
