Hi @Shashank S, a quick glance at your error message suggests a port conflict - the server can't start on port 80. Are you running any other servers on port 80?

There is a file "flexsim webserver configuration.txt" that you can edit to make sure the directories are pointing to the correct locations, to change the port you're serving on, etc. Double check all the info there, perhaps try another port number, save the file, then try again starting the web server.

Comment back to let us know the results.

@Shashank S

Your error-1.png is not actually an error, it is the correct behavior indicating that your web server is running.

You need to visit http://127.0.0.1:8080 to view what is being served, assuming that port 8080 is still the port you have set in your most current "flexsim webserver configuration.txt" as it is in your attached example. Putting the ":8080" at the end of the local IP address 127.0.0.1 is the key to viewing what is being served on port 8080.

Hi @Shashank S / @Ben Wilson

is it possible to post a step by step guide for newbies trying to play with the Flexsim webserver and Flexsim 19.1.x version and above? We have similar use cases for sharing models between teams and end users.

Thanks

@Ben Wilson Thank you for the clarification. I need to work on my IT basics, seems so.

Ben, I am trying to understand the advantages of using Flexsim Web Server over using normal Flexsim instance, but cannot think of any at this point. Can you please give me couple of points to start with ? So I can explore it further from there.

Sorry for asking so many questions and thanks in advance.

@Shashank S,

For regular model building and running, it is definitely better to just use a normal FlexSim instance.

If you develop model that you need others to be able to open and run, perhaps allow them to change a few parameters, and you don't want them to have to install the software or know how it works, that is one use case where the webserver is a valuable asset. In this case the model builder can create the simulation model and host it on a FlexSim webserver. The modeler can create a custom interface allowing the users to change basic things about the model. The users can log in via their web browser, open the model, customize their model settings, run the model, see the animation, get the outputs, etc.

There may be other use cases, but that is the main one.

@Ben Wilson Thanks a lot. I am finally able to make the web server run the models, upload models to it.

Now I Need your help in Hosting the Web Server part as well. How should I go ahead with this ? Does it have any standard process ? Like may be some document.

Does it attract any extra cost if I am sharing my models through web server ?

Sorry for so many basic questions, I am trying to enter in this area for the first time.
