[mapguide-users] Session Creation Issue

[Adam Jamison]

I'm actually not sure how to even explain this issue....

I've been using MapGuide for sometime now and have started using the react viewer, I think it's a great piece of work, I'm not sure if the following error is part of it or mapguide itself.

The issue is the application renders fine on 95% of my users browsers, however a few are experiencing some issues:

  *   The interface renders correctly
  *   From all points of view the session is created and active
  *   All external layers render
  *   The user is using Chrome
  *   The user is receiving the following error: Failed to load resource: the server responded with a status of 559 (MgInvalidArgumentException)
  *   If the user accesses the site via Edge Browser it loads correctly...
  *   If the user accesses the site from another PC it works correctly...

I don't know how to debug or even investigate...

I've tried:

  *   Rebooting server
  *   Restarting IIS
  *   Restarting MGServer instance
  *   Clearing chrome browser cache / history
  *   Using a username and password
  *   Kicking the PC
  *   Intimidating stares ><
  *   Trying to clear php sessions on the server
  *   Starting a session on another PC and copying the URL to the effected users PC

I'm confused as it's only effecting that user on the one specific PC, even loading the site as another user on the same PC works....?

I think it has something to do with the user accessing a session created in the office then trying to pop back into the same session when they take their laptop home and connect via the VPN, or trying to access another users session using the sessionId (also would kind of expect this just to work?). some kind of permission thing ... it's not creating all the resources to correctly initialize the map....?

This is on the MapGuide 4.0.0.10048, Windows 10.0.19045 Build 19045 (Version 22H2 OS Build 19045.2604), IIS (Version 10.0.19041.1)

  - MgRenderingServiceHandler.ProcessOperation() line 83 file C:\working\build_area\mapguide\4.0.0\x64\MgDev\Server\src\Services\Rendering\RenderingServiceHandler.cpp

  - MgOpQueryFeatures.Execute() line 125 file C:\working\build_area\mapguide\4.0.0\x64\MgDev\Server\src\Services\Rendering\OpQueryFeatures.cpp

Open to any suggestions at this time.

I'll go through any changes I've made to see if I've effected the session creation at some stage....

Adam
