Octoprint not running after changing port

Hey there! My problem: when I open octoprint in my browser, I get the "server is currently not running" site.

So I installed octopi on my raspberry pi 3B+, configured it for my network and set it up.
After that, I changed the frontend port to 81 and the ssl to 444 (in haproxy.cfg) and installed apache2+wordpress+noip2 to host a website on port 80.
Then I wanted to log in to octopi on port 81 but after reloading I always got this site " The OctoPrint server is currently not running".
I followed the steps and tried this command: "pi@octopi:~ $ ps -ef | grep -i octoprint | grep -i python" and got no output.'
.octoprint/logs/octoprint.log says:

(And I obviously tried to restart octoprint and reboot the pi too.)
I'm sorry for pasting in so much code but I wanted to make sure that there isn't missing a thing.

After searching through the forum, I found that after this "~/oprint/bin/octoprint serve" I get this: 2019-08-24 11:30:43,247 - octoprint.startup - CRITICAL - Could not initialize settings manager: Folder at /home/pi/.octoprint/scripts doesn't appear to be writable, please fix its permissions 2019-08-24 11:30:43,247 - octoprint.startup - CRITICAL - There was a fatal error starting up OctoPrint. Could not initialize settings manager: Folder at /home/pi/.octoprint/scripts doesn't appear to be writable, please fix its permissions There was a fatal error starting up OctoPrint.
After giving permission (sudo chmod a+w path_to_the_file) I got this:
octoprint.startup - CRITICAL - Could not initialize lo gging: Unable to configure handler 'file': [Errno 13] Permission denied: '/home/ pi/.octoprint/logs/octoprint.log' octoprint.startup - CRITICAL - There was a fatal error starting up OctoPrint. Could not initialize logging: Unable to configure handler 'file': [Errno 13] Per mission denied: '/home/pi/.octoprint/logs/octoprint.log' There was a fatal error starting up OctoPrint

Thanks in advance!

At some point you apparently managed to break the permissions of the whole config directory. Used sudo for something that doesn't need it by any chance? That would do it.

To possibly fix (and yes, here you do need sudo here):

sudo chown -R pi:pi /home/pi/.octoprint

Is it a colon or a period there between user:group?

It was a period, but it should have been a colon. Thanks for the catch.

The top dot was probably off getting coffee somewhere...

In my defense, . and : are the same key on a german layout, so a half hearted shift press is all that it takes :wink:

If I recall correctly, there was a time when you could use a . instead of a : in chown syntax.

That would explain why it didn't look wrong to me. A long time ago in a galaxy far far away I used to be a Linux & Solaris sysadmin...

Hey guys!
Thanks for the help and sorry for the late response.
I tried to fix it with "sudo chmod a+w all_files_which_were_making_problems" and it seemed to work. Probably sudo chown -R pi:pi /home/pi/.octoprint would be the better solution.

BUT: After that, I set up octoprint, apache, wordpress and noip on a completely new SD Card and this time I didn't got any issues.

Thanks for helping though!
