Totally baffled on web site error ...

[RCPWISC]

Hi everyone:  I'm relatively new to Linux Lite, but what I'm experiencing has me completely baffled.  We recently got set up with a POS software program (run via a web site) that allows us to process credit cards.  I had an old HP pc laying around, and thought this would be a perfect use for it, as it would only be used for this sole purpose.  I installed the OS, loaded up the web site in Firefox, and when I get to the point to submit the transaction for processing, the web server responds with an error.  It's not a standard error or a browser error - it's an error generated by the POS web server stating it cannot process the transaction, and it instructs me to refresh the browser.  I do that, and it's an endless circle.

I tried the POS web service with Firefox, Chromium and Google Chrome, and all three refused to process the transaction.  For grins, I tried processing on my Windows PC using Google Chrome, and it went through without an issue.

What am I missing here?  A web browser is a web browser ... what would make this work on a Windows browser, but not work on a Linux browser?  I'm totally at a loss ......

Thanks for any light you can shed on the subject!

Hell RCPWISC,

does the Firefox browser in LL have cookies enabled ?
are there any ad blocking, or other addons added ?
do you have the restricted extras installed in LL
does the POS software require Java?

If not one of the above more information, not personally identifying or site identifying, may help one of the community to help you.
Eg;
which version of LL are you running that HP pc?
which version of Firefox on Linux and Windows?
what is the POS software brand, and its version ?

First off... Welcome to the forum!!!


You are mostly correct a browser is a browser but an OS is an OS...  ;D ;D
The browser can and most times will report the OS its running on, if not an "approved" OS it can fail.


What you may want to try it a "User Agent Switcher addon" - Where Firefox will then report its running on another "approved" OS...


If the application is strictly web based I don't see where any issues would occur, although should there be calls back to the OS the add-on still may not work..


Just for fun, another thought would be to query the POS software support to see about adding Linux as a supported OS 


I personally have never used or needed to use the switcher..

You don't say what OS you're running. Be aware that many web secure transactions now require at least a Firefox version 52 ESR or newer. If you are using LL3.4 updated then you are okay that way. Try firenice03's suggestion. You may have to allow a data port entry in your firewall also. The warning you are getting sounds like your browser is not new enough, or you have disabled redirect in your browser. Just going off your user name maybe you're from Wisconsin. I'm close to Lake Geneva. I might be able to help in person. Let me know.

Thanks for the welcome everyone.  OK ... tried some stuff today, and will answer your questions below:

-I'm running the latest version of LL.  Just downloaded and installed last week.

-Firefox Version is 54.0

-Cookies are enabled in Firefox.

-Restricted extras are installed.


-We're using a POS web site through our payment provider, e~Funds for schools.  You can see the page by going here:
https://lbs.mvpbanking.com/efs-p2/index.html#!/  The POS software version is 1.3.1.15

-I tried following the instructions to put in the User Agent String.  I opted to use the option without the addin.  I created the string, and used the following data for the string: [pre] Mozilla/5.0 (Windows NT 10.0; WOW64; rv:40.0) Gecko/20100101 Firefox/54.0[/pre]

-I also tried the UserAgent web plugin for Firefox.  No dice there, either.

That didn't do the trick.  Web site is still rejecting the transaction.

For the heck of it, I burned another USB drive of LL and booted it and installed Google Chrome.  Same thing - it wouldn't process the transaction.

I also tried a few different "flavors" of Linux that could boot from the USB flash drive, and they all had the same problem.  That's telling me that there's something going on in the OS.  If one of the browsers would work, I would tend to think that the browser could be the culprit, but if all of them aren't working, that's leading me to believe there's something that either needs tweaking in the OS, or I suppose it could be that this POS web site just won't work with Linux.  It continues to be a mystery!

I'm happy to try other suggestions ...  Thanks for the help!

Is there a debugging option available so that you can see what is going on when the browser tries to do it's thing?

You could also try Internet Explorer in Playonlinux as a test. Google 'Playonlinux install Internet Explorer 8'. Playonlinux is available via Lite Software.

security key may be the issue. turn off your firewall completely.

[RCPWISC]

Thanks for the continued assistance.

I tried disabling the firewall using [pre]sudo ufw disable[/pre].  No help.

I installed PlayOnLinux and Internet Explorer 8, but the web browser refused to visit the page.  It loads a few pages, but most of them come up as not reachable. 

I'm thinking there must be some strange compatibility issue ........
