Electron version v14 to v15 update Problem

I have the following problem and now after several days still can not solve it.
I am upgrading an Electron app from version 12 to version 22. The app is there to make certain data packages of our customer more manageable. I have already managed to update the app to version 22, but there is still an error that occurred when updating from version 14 to version 15.
To log in to the app, the external login page of our customer opens in a second window of the app. The login is handled there. I only get back whether the login was successful or not. Afterwards it is checked if the file packages are up to date or if updates are available ect.
So far, everything works fine. But from version 14 to version 15 of Electron there is a problem. The login works, but the following query for updates ect. fails. This query is only possible if you are logged in.
In the Developer Tools I see that I get redirected from request url to the login page. As far as I understand, the Problem is related to the cookies. As if the query would not have access to the cookies of the successful login. But when I look at the breaking changes of version 15 I don't find anything about it.
Does anyone know what the problem could be or how I could fix it?

SQL changes are not displayed in Angular with .NET Core

I have a project that is written in .NET Core 3.1 and Angular 7. I was hosting this project on a server until yesterday. I had to migrate this project to another server. After the migration, I started to have some issues. Whenever I change any SQL data, the Angular component is not refreshed and not displayed the current changes. However, testing it locally, it was fine and works as expected. But when I deployed to the new server, this problem happens.
Specifically, I have a form that I update the users. The update process is working as expected. Not receiving an error. But When I try to edit it again for test purposes, I see unedited data even though SQL database has the edited data.
I did research and found that this question has been asked here already. I followed all of the answers. The issue was not fixed. After that, I thought this could be an SSL issue because .NET Core 3.1 uses SSL for retrieving data. So I even downgraded to 2.1 but I still have the same issue.
The project is working fine with the old server and locally. But I have this issue with the new server after the deployment. I am not sure what to do after this point. Any help would be appreciated.
After a long research, a lot of debugging and modifications, I found out that (in my case) the issue is not related to .NET core nor Angular. The server has set up that is doing some caching for all sites that go through the proxies for increased performance. This certainly did cause the issue I have. Caching has been removed and everything started to work as expected.

Program showing fine in browser but fails to load resources in electron window

Currently working on a project and everything was working fine. Then suddenly after rebooting from a power cut whilst working on said project, the electron application has since failed to load any online resources. It works perfectly fine when on a native browser using localhost but will fail to load any online resources on the electron application version.
Initially, I thought it was a firewall issue but changing settings has not changed anything. I've reset router/pc multiple times to no avail.
The error recieved for any online resource is GET [URL] net::ERR_EMPTY_RESPONSE
Edit: Here is a screenshot of the error displayed in electron:

Gmail gadget not refresh although nogadgetcache=1 parameter is used

Problem Description: deployed a new gadget xml but gadget does not refresh although parameter nogadgetcache=1 is used.
Steps to Reproduce:
i makes changes to a gadget xml. Deploy using Eclipse, to an appspot site.
2, Deploy through code.google.com's google app console ( i think this is only for changes to manifest, but with or without this step, refresh does not happen ).
Able to see latest changes on the appspot site hosting the gadget xml
logout of gmail, login with : https://gmail.com/?nogadgetcache=1
gmail gadget behaves like the old version.
Even stopped development for more than a week, still not refreshed.
Anyone here can help or encounter similar issues?
Try renaming the gadget spec file so it uses a new URL (then update your manifest to reflect this new URL). This is from Google's documentation.
we have the same problem it take 30mins to get it work..

i found the problem in chrome take's very long.. if you do it in internet explorer prived mode it much quicker..

.Net MVC4 Wrong Views Displayed (.mobile issues)

Recently I added a mobile version of the site using MVC4 .mobile views. I structured the site in a very similar way to the desktop version by starting from _Layout.mobile.cshtml which pointed to the correct scripts and css designed specifically for the mobile site.
After publishing the site I checked that everything worked correctly which it did just as how it was designed. But shortly I was told that the site was broken. When checking the mobile site I noticed that the _Layout.mobile.cshtml was loaded but instead of the Index.mobile.cshtml which is sent from the Home controller, what was returned instead was the standard Index.cshtml designed for desktop. The desktop Index file was also rendered using the mobile css which caused the whole mobile site to look very messed up. On a side note, no changes occurred to the desktop version of the site.
Republishing fixed the issue, but I also noticed that sometimes it reverts back to displaying the correct views without republishing even after it broke.
I began to research the issue and what I stumbled across discussions about Display Modes not working such as this:
ASP.NET MVC 4 Mobile Display Modes Stop Working
With a NuGet solution that read as deprecated: http://www.nuget.org/packages/Microsoft.AspNet.Mvc.FixedDisplayModes
I assumed that since this discussion was from a year ago talking about early releases it should be fixed by more recent MVC4 updates. My current version was 4.0.20710.0 so I updated to 4.0.30506 using NuGet before doing anything else.
This did not solve the issue but not only that, upon inspecting I noticed the reference System.Web.MVC was still pointing towards the 4.0.20710.0 version dll file.
I am worried about adding an unnecessary fix that is labeled deprecated and was hoping that the MVC update would resolve this issue. Any suggestions?
the package in your link is the package for the pre-release Asp.Net MVC 5. Indeed, they did solve the issue you are having in the Asp.Net MVC 5 package, but it is still pre-release with Visual Studio 2013. In the additional links on the page, there is a link for the non-beta, non-RC release that still applies to Asp.Net MVC 4 (FixedDisplayModes)
