Cannot connect to tomcat server - linux

I am trying to install tomcat in a Ubuntu Server machine.
At first i installed tomcat8 through apt-get and i was able to connect. Then i tried to add some webapps for dspace, and from the time i added them, i cannot connect to the 8080 port. I removed the webapps and still i couldn't connect.
I already tried to reinstall tomcat, then i manually installed tomcat and i also tried tomcat 7 and 9, but i couldn't resolve my problem.
I tried to change the port, and I had the same problem. Also there are no other programs using this port.
I tried apache server at port 8080 and it works, so there shouldn't be a problem with my provider or firewall.
Also, the catalina.out log doesn't have any warnings.
Any ideas before I make a fresh install of the Server?

Just minutes after i posted this, the server responded to the browser after 10 minutes waiting.
I found this solution and it worked
Tomcat7 starts too late on Ubuntu 14.04 x64 [Digitalocean]

omnetpp does not start on Ubuntu

I use Ubuntu-20.04 via wsl. There, I have installed ometpp-5.6. Also, on Windows, I have installed VcXserver to run onmetpp IDE.
But when I run in the command prompt on Ubuntu omnetpp I get Starting the OMNeT++ IDE..., but no IDE window is being open, even though I have configured my environment as described here.
How could I solve my problem?
Adding separate inbound rule for TCP port 6000 as described here solved the issue.

OpenSSH server wont install on azure Windows 10 VM

I'm trying to install OpenSSH-Server on multiple Windows 10 VM from Azure.
I added some rules on network security group (directly on portal.azure) : I allowed inbound traffic for port 22 and same for outbound.
After that I tried to install openSSH-server using the windows 10 interface, but it doesn't work (no error message, just jumping back into the app list).
I tried to add the rules to the firewall and retried to install openSSH-server, no success.
I also tried to install it using powershell but without success.
There is something I must be missing, here is the guide I followed for installing OpenSSH-server: https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse
And here is the guide I followed for opening ports:
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/nsg-quickstart-portal
Ok so I finally find out what was blocking the installation, the Windows update service was deactivated, by activating it I was able to install OpenSSH-Server, all good now !

What am I doing wrong?
Nvm. Got it working. I had not installed the expected dependencies in it. Like php.

Run artifactory on browser

I installed artifactory on linux server. I want to know how to check whether it is properly installed.
Secondly, I want to use it's user interface on google chrome. From where I can get SERVER_DOMAIN and PORT number for it's url from installed files on server?
Thanks in advance.
Your question is a bit vague.
How did you installed it (ZIP, RPM, Docker, Deb...)?
Which database you used (default, Oracle, MySQL etc..)? You can see if the server is up and running by running the following REST API from the machine you have installed it on:
curl -iuadmin:password localhost:8081/artifactory/api/system/ping
Regarding the IP, this can be checked by running 'ifconfig' on the linux server and get the IP of that machine.
Artifactory by default is running on port 8081, unless you changed it.
It seems that you will need to follow the basic installation wiki:

Installing IIS on windows 10

I'm trying to connect Java to mysql on a windows 10 machine. I was told that I first needed to install IIS. I've done this but when I go to localhost in my browser I get:
HTTP Error 500.21 - Internal Server Error
Handler "StaticFile" has a bad module "DefaultDocumentModule" in its module list
I'm not sure what to do at this point
I uninstalled IIS and reinstalled and now it works
