sometimes it works sometimes it doesn't works "Failed to load resource: the server responded with a status of 500"

Hello everyone.
A year ago I uploaded a website to an IIS platform and it worked fine.
There have been malfunctions lately.
The site manages the students of a school and if I open a certain page with the data of a certain student, every event I trigger I get the error: "Failed to load resource: the server responded with a status of 500". I thought it was a code error, but if I log in locally via IP address the error does not occur.
No errors are reported in the IIS log files. I developed the site with VB.NET using the 4.0 Framework.

if he opens the student page Marck with the website website.com\student.aspx ERROR
if he opens the student page Maria with the website website.com\student.aspx OK
if he opens the student page Marck with the website 192.168.1.1\student.aspx OK

I have no idea where the mistake might be.
the only suspicion I have is that it is a communication error with the IIS that leaves the communication hanging. but i don't know.

update: in the student data there is also a field with a slash inside (/) , when the slash was removed, the page started working again. could it be a localization problem?

This does not completely solve the problem for me. because another student with the slash in the data does not give me the problem.

The real problem is that I don't know what to look for anymore. A new clue would be enough for me. Tell me what you need and I'll write it to you.


update 2: when I insert the value "16/2" it doesn't work, instead if I insert in the inputbox "16/2." or "16/2g" works.


If I enter in the inputbox, numbers + slash + numbers does not work. In other cases it works.

For me it doesn't interpret the slash correctly. Is there any way to correct the formatting?

@CKK5L-8070 It is difficult to reproduce your problem based on this messages, I suggest you use failed request tracking to view detailed error information.
