Lora-app-server web Interface/Gui Not Opening on a specific browser

I just encountered this minor defect from browser of one specific machine.I can see the login screen of the GUI. but after logging in its just a blank page like this,Although this dint occur for rest of the physical devices

.

Even after clicking on organization the url changes in the address bar yet nothing happens

what do you think is wrong ??

I see that you have Internet Explorer as well. Did you try with that browser as well?

With self-signed certificates I sometimes notice that part of the page is cached and part not loaded because the certificate is invalid. The result: part of the page is rendered but because the browser is not noticing me about the self-signed certificate, the rest is not loading. This can be resolved (at least at my side) by refreshing the page.

So basically buying a SSL certificate will resolve the problem??

I get the same problem in internet explorer as well.
