MAMP no longer prompt for a password and Apache won't start

After an upgrade to MAMP 6.7 on macOS Monterey, MAMP no longer prompts for a password and Apache won't start.
At MAMP start:
MySQL starts
Apache doesn't start
I must execute /Applications/MAMP/bin/startApache.sh in Terminal to start Apache
At MAMP stop:
I must use /Applications/MAMP/bin/stop.sh
Until this update (to 6.7), MAMP asked me for a password every time I started.
I tried several solutions found here. Same problem with port 80 or 8888. At each test, I kill all HTTPD or MYSQLD process. Renaming or deleting envvars does nothing.
It seems that MAMP can't execute startApache.sh.
Edit :
The last update 6.8 solve this issue : https://www.mamp.info/en/release-notes/mac/#v6.8
It seems that MAMP found something about this issue : https://www.mamp.info/en/release-notes/mac/#v6.8

How to get rid of PWA on port 8080

I tried developing a PWA few weeks back and tested it on http://localhost:8080. I have stopped working on that project now, but still when I http://localhost:8080 it still contains the home page of the PWA. I tried to kill the process on 8080 using the PID but the PID it give is 4 and when I try to kill the process using cmd or powershell (with run as admin) it says
ERROR: The process with PID 4 could not be terminated.
Reason: Access Denied.
It would be great if someone can share share some thoughts on what to do here

Kibana/Elasticsearch/logstash install issue

I have an issue installing Kibana/elasticsearch/logstash.
I followed the instructions for the download and the install of each. From the Admin CMD line, I ran the elasticsearch.bat for elasticsearch. The script ran, but just hung and never fully completed. However, when testing on my localhost 9200, it showed ES installed correctly. I did the same with Kibana and had the same result. The script never fully completed, however, I was able to open the web app on port 5601. I also completed the install for logstash – the script never fully completed. When I manually exited each script by exiting the cmd window, I lost connection to the localhost. "This site can't be reached."
Has anyone had this issue or know what might be happening here?

Has anybody run Xvfb on EC2 with CentOS?

I am trying to get javascript-enabled cucumber running on CentOS in EC2 by following this tutorial: http://makandra.com/notes/1391-how-to-hide-your-selenium-browser-window-with-headless However, the scenarios that require javascript just fail without any exception message.
In order to debug, I just went to see if Xvfb is working correctly with according to this tutorial: http://blog.kabisa.nl/2010/05/24/headless-cucumbers-and-capybaras-with-selenium-and-hudson/
I tested the command:
Xvfb :99 -ac -screen 0 1024x768x16
I got the error msg like this:
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/ip-10-116-82-44:99
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
I googled for solutions about of these errors. I haven't found a good solution for this yet. If I run the same command again, I get:
Fatal server error:
Server is already active for display 99
If this server is no longer running, remove /tmp/.X99-lock
and start again.
So the server is supposed to be up and running already. However, when I tried to run this in followups:
DISPLAY=:99.0 firefox http://www.google.com
The console just hangs there, until I contol + C to kill it.
Is there anyone who knows what's going on here?
Thanks in advance.
It seems that it's okay. Your console didn't hang - it is firefox is working - you just don't see it:)
Edit: I think you can connect there with ssh -X and you'll see firefox window if it is working. (Only if you're running linux/mac on your dev machine)
